5.0 CHAIR’S REMARKS & REPORT – DON PLATTS
The Chair’s Report was presented at the Monday General Session.
Highlights:
Don opened welcoming the attendees to Memphis.
Don discussed the Tech Council. He indicated that none of the discussed topics affect this group. The
primary topic was the reorganization of the PES Technical Committees. There were some significant
changes to some of the other Technical Committess. There was a proposal that solid state TRs and energy
routers should be covered under the Transformers Committee, however, when questioned on who to
contact at the various organizations to coordinate, there were no answers readily available. Until further
information is provided, no changes to our Committee will be made.
Don mentioned that Bill Bartley after many years of service in the role of Standards Coordinator, would be
stepping down and that Tim Holdway would be taking his place January 1. In addition, in January there
will be a transition of the officers with Steve Antosz moving into the position of Committee Chair, Susan
McNelly into the position of Vice-Chair, and that Bruce Forsyth would be moving in to the position of
Committee Secretary.
5.1 CHAIR’S REPORT – PRESENTED AT THE MONDAY GENERAL SESSION
5.1.1 IEEE Power & Energy Society Technical Council
The Technical Council of the IEEE Power Energy Society (PES) is presently composed of the
Chairpersons of the PES Technical Committees, plus the Chairpersons of Standing Committees reporting
to it. The Power Energy Society is Division VII of The Institute of Electrical and Electronics Engineers
(IEEE). For operating functions it is responsible to the IEEE Technical Advisory Board and for technical
activities to the IEEE Technical Activities Board.
The PES Technical Committees report to the Technical Council on matters concerning membership,
technical publications, recognition, scope and the coordination of the Power Energy Society generated
standards. For standards relating to their technical scope, the Technical Committees work directly with
the IEEE Standards Board and the Power Energy Society Standards Coordinating Committee.
Please see http://www.ieee-pes.org/statement-of-purpose-and-scope-of-activities-for-the-pes-technical-council
for further details on the Statement of Purpose and Scope of Activities for the PES Technical Council.

5.1.3 PES Technical Council Activities
The Tech Council is undertaking a project to ensure that the activities of each of the technical
committees fits within their scope, and that each has an updated O&P manual, and those that write
standards also have a current P&P.
It appears that as some new technologies develop, they do not fit into the scope of the present
committees, or that they may fit into several possible places due to scope overlaps, or gaps in the scopes.
A program is underway to realign the technical committees with the industry today. To implement this,
the present list of 21 Technical Committees and Coordinating Committees will be reduced to 19. The
reorganization has resulted in nineteen coordinating and technical committees as shown below.
1. Intelligent Grid & Emerging Technologies Coordinating Committee
2. Marine Systems Coordinating Committee *

5.1.4 Update on Geomagnetic Disturbance (GMD) Taskforce
The Technical Council Taskforce on GMD has made no progress this year on the development of the
position paper, and little progress since last Chair’s report in October 2013. The task force was able to
complete an initial release of an article entitled Geomagnetic Disturbance and Its Impacts on the Power
Grid in the PES Power & Energy Magazine in the July, 2013 edition to coincide with the GMD Super
Session held at the PES General Meeting in July, 2013 at Vancouver Canada. This project continues to
fall further behind schedule, primarily due to fundamental differences of opinion of some of the
contributors. The IEEE PES Technical Council still maintains strong support for the project and has
urged the task force to proceed with the completion, even if the report needs to be a Stage 1 report,
subject to revision and additions as time passes and knowledge grows. The chair has been waiting for
the PES Transformers Committee working group to produce a Guide that has recently been published.
With that document as a background, the Chair has a plan to try to move the participants toward
completion of the project by later this year.
5.1.5 Transformers Committee Activities
Officers Progression for the 2014-2015 Period

5.1.6 What You Need to Know About IEEE Standards and the Law [an excerpt]
IEEE standards should be relevant and respond to regulatory and market needs. They should not
distort the global or domestic market, have adverse effects on competition, or stifle innovation and
technological development. Efforts should be made to avoid duplication or overlap with other
standards, especially international standards.
Wherever appropriate, IEEE standards-developing groups should specify standards based on
performance or function rather than design or product specifications.
The full brochure can be found at:
https://standards.ieee.org/develop/policies/stdslaw.pdf
5.1.7 The Standards Board Operations Manual
The following text has been approved by The Standards Board and will be implemented into our
Operations Manual in January 2015. The accompanying text may provide an opportunity to educate
the committee members as a whole. "5.4.3 Conduct of the standards balloting process
The ballot process may include communication among the Sponsor comment resolution group and Sponsor balloting group
members regarding the substantive merits and possible resolution of comments. However, no comment resolution member,
Sponsor balloting group member, or standards participant shall intimidate or coerce a specific vote from any Sponsor
balloting group member."
IEEE-SA supports communication among participants and members as a part of the technical discourse or
comment resolution, and advocating a personal view or opinion can be a part of the discourse. However, the WG
or TF should be mindful not to give specific recommendations and proposed text with instructions to other
members. This could be seen as a form of coercion for a specific vote, which violates Clause 5.4.3 of the IEEE-
SA Standards Board Operations Manual, "Conduct of standards balloting process."
Within our committee we want to operate in a manner that does not give the appearance, or cause anyone to
perceive, that our actions would result in collusion or coercion by any members or activity leaders.
5.1.8 IEEE Standards Association (SA) Requirements
IEEE SA’s Role
In the course of developing our standards, we as volunteers while having the best interest of advancing
the technical understanding of our industry, are no doubt also influenced by those who sponsored our
participation with other interests that potentially could influence our decisions. This is where a good
understanding of the IEEE SA’s role and its relevant policy and procedures will help in clarifying
some of the dos and don’ts in the process of developing our standards.
IEEE SA is a standards development organization that: Develops voluntary standards, recommended practices, and guides
Uses an accredited process that promotes consensus building among those with material interest in any
given technology, and is based on proven imperative principles of openness, consensus, balance, due
process, and right of appeal
Oversees the process by which consensus is reached
Has standards that are adopted by regulatory agencies and international bodies around the world
Promotes standards implementation, but does not define laws or regulatory requirements
Defines technical requirements, not market mechanisms
Reviews documents based on technical merit, and established scientific findings
IEEE SA does not: Test or verify the content of standards
Assure health or safety
Make guarantees
Make warrantees
Establish law or regulation
Define essential patents, essential patent holders, or licensing terms
Define commercial terms or market mechanisms
Infer that an IEEE standard endorses products, services, or companies
Press Releases Policy Relating to IEEE SA Work & Products Press releases about IEEE standards by outside entities without approval by IEEE:
Cannot claim that the IEEE standard endorses a product, service, or company
Cannot claim that the standard establishes requirements based on information in informative text
(including informative annexes)
Cannot include marketing text about IEEE or IEEE-SA that may infer endorsement by IEEE or IEEE-SA
Must clearly indicate that all statements are that of the entity and does not necessarily represent a position
or opinion of either IEEE or the IEEE Standards Association
IEEE SA Disclaimers
A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board
Operations Manual shall not be considered the official position of IEEE or any of its committees and
shall not be considered to be, nor be relied upon as, a formal position of IEEE. At lectures, symposia,
seminars, or educational courses, an individual presenting information on IEEE standards shall make it
clear that his or her views should be considered the personal views of that individual rather than the
formal position of IEEE.
5.1.9 IEEE Code of Ethics
The IEEE Code of Ethics serves as the guiding light to keep us focused on maintaining and evolving our
culture that makes the Transformers Committee one of the best technical committees in the Power &
Energy Society’s area. Below is the excerpt from the IEEE Policies, Section 7 – Professional Activities.
Affiliation
Given the core objectives of the standards development process to follow the concept of “openness”
and “due process” in that it allows for equity and fair play we need to strive to have a balance of
interests and not to be dominated by any single interest category. Moving forward, the disclosure of
participants’ affiliation shall include not just who you are, but also who is your financial sponsor.
5.1.10 IEEE Membership – Senior Grade
IEEE membership has several categories, with the senior level being the highest grade which a member
can apply. IEEE has developed a streamlined process for members to request elevation of their
membership status. The process is simple and can be done entirely online. The Chair strongly
encourages everyone that has been an active contributor to the industry for at least five years to apply for
this elevation in membership status. The basic qualifications are: be engineers, scientists, educators, technical executives, or originators in IEEE-designated fields;
have experience reflecting professional maturity;
have been in professional practice for at least ten years;
show significant performance over a period of at least five of their years in professional practice.
Benefits of becoming a senior member include: Recognition: The professional recognition of your peers for technical and professional excellence.
Senior member plaque: Since January 1999, all newly elevated Senior members have received an
engraved Senior Member plaque to be proudly displayed for colleagues, clients and employers. The
plaque, an attractive fine wood with bronze engraving, is sent within six to eight weeks after elevation.
US$25 coupon: IEEE will recognize all newly elevated Senior members with a coupon worth up to
US$25. This coupon can be used to join one new IEEE society. The coupon expires on 31 December of
the year in which it is received.
Letter of commendation: A letter of commendation will be sent to your employer on the achievement
of Senior member grade (upon the request of the newly elected Senior member).
Announcements: Announcement of elevation can be made in section/society and/or local newsletters,
newspapers and notices.
Leadership Eligibility: Senior members are eligible to hold executive IEEE volunteer positions.
Ability to refer other candidates: Senior members can serve as a reference for other applicants for
senior membership.
Review panel: Senior members are invited to be on the panel to review senior member applications.
US$25 referral coupon: Newly elevated Senior members are encouraged to find the next innovators of
tomorrow and invite them to join IEEE. Invite them to join and the new IEEE member will receive $25
off their first year of membership.
IEEE Membership – Fellow Grade
The IEEE membership grade of Fellow recognizes unusual distinction in the profession and shall be
conferred only by invitation of the Board of Directors upon a person of outstanding and extraordinary
qualifications and experience in IEEE-designated fields, and who has made important individual
contributions to one or more of these fields. IEEE Fellow nominees are classified into the following
four categories: Application Engineer/Practitioner
Educator
Research Engineer/Scientist
Technical Leader
IEEE Fellow is a distinction reserved for select IEEE members whose extraordinary accomplishments
in any of the IEEE fields of interest are deemed fitting of this prestigious grade elevation.
According to IEEE Bylaw I-305.5, the total number of Fellow recommendations in any one-year must
not exceed one-tenth of one percent of the voting membership on record as of 31 December of the year
preceding. At the time the nomination is submitted, a nominee must: have accomplishments that have contributed importantly to the advancement or application of
engineering, science and technology, bringing the realization of significant value to society;
hold IEEE Senior Member or IEEE Life Senior Member grade;
have been a member in good standing in any grade for a period of five years or more preceding 1
January of the year of elevation.
For further details please refer to the website
http://www.ieee.org/membership_services/membership/fellows/index.html

The Transformers Committee AMS database of people currently has three general categories of
participation in our activities. These are: Interested Individual, Active Participant, and Committee
Member. Anyone can join the AMS 123 system as the system is designed for self-registration. A new
participant will automatically be assigned the role of Interested Individual when they first sign up. Based
on the level of participation, the committee administrative staff will upgrade the participation status to
“Active Participant” when appropriate. The Committee Member status however, can only be attained
through a formal application with the sponsorship of a minimum of three WG or SC chairmanships.
Details of the application requirements and approval process by the Administrative Subcommittee are
outlined in our O&P manual.
The following table contains a count of the participants grouped by the three general categories (CM totals

The Committee welcomes and encourages active participants to become Members of the Committee.
Requirements and application forms can be found in the Organization and Procedures (O&P) Manual,
accessible on the Committee website. A link to the Membership Application form can be found on the
TransformersCommittee.org homepage in the Committee Information Box. Subcommittee Chairs are
encouraged to recommend new members and to communicate the process of attaining membership through
active participation and contribution at the WG and SC level. WG and SC Chairs are reminded also that
signing an application sponsoring a new member signifies their sponsorship that the applicant has met the
requirement of membership and active participation for at least one year in the WG or SC they Chair. New
member applications may be submitted to the Committee Secretary’s attention at any time. Applications
will be collected for review and approval in batches at each Administrative Subcommittee meeting.
7.3 COMMITTEE, SUBCOMMITTEES, AND WORKING GROUP ROSTERS
In order to provide indemnification to working group and subcommittee members it is crucial that
membership lists be maintained. The AM system has these functions built-in to ease these administration
tasks. It is important that each subcommittee and working group chair keep the rosters updated so that this
information can be provided to the IEEE SA.
A similar main committee roster has also been developed to track attendance for the Main Committee
General Session meeting on Monday & Thursday. The data will be used to update participant’s
membership profile.
7.4 IEEE/PES AND IEEE/SA MEMBERSHIP REQUIREMENTS
As a reminder, all members of the Transformers Committee must also be members in good standing of the
Power & Energy Society (IEEE/PES) and the Standards Association (IEEE/SA).
WG Chairs must also be a member of the SC, IEEE, PES, and SA.
7.5 COMMITTEE MEMBERSHIP MAINTENANCE
The following 12 members were revised to the status of Past Committee Member: Dennis Allan, Bill
Darovny, Alan Darwin, Marcel Fortin, Saurabh Ghosh, Dave Harris, Joseph Kelly, Dennis Marlow, Dan
Perco, Paulette Powell, Timothy Raymond, and Vallamkonda Sankar. Robert Olen was removed as he has
not attended for several years and is no longer in the AM System. There are several other members who
have not attended for several meetings. Notices have been sent and their status will be changed unless they
respond with intentions of attending/participating in the Committee.
Scott Reed has requested reinstatement of his membership status from Past Committee Member to
Committee Member. Mr. Reed has attended the last two meetings and is registered for the Fall 2015
Memphis Meeting. Approval by the Administrative Committee will be required.
7.6 ESSENTIAL PATENT CLAIMS
The Transformers Committee asks each participant at the time of meeting registration if they are aware of
an essential patent claim, and if so to provide details. An Essential Patent Claim is any Patent Claim the
use of which was necessary to create a compliant implementation of the IEEE Standard when there was no
commercially and technically feasible non-infringing alternative. In other words, if an IEEE Standard
REQUIRES the use of a product or process that is already patented, then this could be an essential patent
claim. If they did, they would be instructed to have the patent holder’s legal team file a Letter of
Assurance (LOA) with the IEEE-SA Standards Board Patent Committee. There is a link to this
information on the transformerscommittee.org website under Patent Disclosure Requirements.
For the Fall 2015, Memphis meeting, most people indicated No to the Patent question. There were 6
people who answered YES that they were aware of an essential patent claim. Of these, 3 provided no
details and were therefore not considered any further. The remaining 3 were reviewed:
1. referred to C57.139 - Letter of Assurance sent to IEEE Jan 2013,
2. referred to PC57.147 Guide for Acceptance and Maintenance of Natural Ester Insulating Fluids
in Transformers and Other Electrical Equipment, Insulating Fluids SC, Eaton/Cooper,
3. referred to PC57.147 and C57.155 (Insulating Fluids Sub) deal with Essential Patent Claims for
which there is no LOA by Eaton Corporation, the patent holder. If there has been an informal
agreement between the Transformers Committee and Eaton/Cooper, in lieu of a LOA, can we be
told about it, to determine if we, the users and writers of these guides can be held liable for
infringement of the subject patents?
7.7 AFFILIATION
According to the IEEE Standards Board Bylaws, there is a requirement that participants of an IEEE
meeting must disclose their employer and affiliation. Consultants must state if they are sponsored, or not.
One cannot simply announce that "My name is John Smith, and I'm a consultant." If a client is sponsoring
an attendees presence, it must be disclosed. If the consultant does not have a sponsor, the proper
introduction is something like.”My name is John Smith, I am a consultant, and I represent myself at this
meeting.”
7.8 MEETING MINUTES
The minutes of the Spring 2015 meeting in San Antonio were posted to the committee website in August
of 2015.
Subcommittee Chairs are requested to submit their SC Minutes for the San Antonio meeting before Jan 1,
2016. It is important to have timely submittal and review of the minutes while the activities are still fresh
in member’s minds. This helps ensure that accurate minutes are
The minutes should be submitted via e-mail to the Committee Secretary, Susan McNelly
[[email protected]], who will also make sure that they are posted on the Committee website.
The submittal file should be saved as a Word document formatted Similar to this document. Attendance,
indication of quorum, names of members making any motion, seconding any motion, and the result of any
votes (affirmative and negative count) for each SC, WG, and TF meeting are to be included in all minutes.
Respectfully submitted,
Susan McNelly

8.0 TREASURER’S REPORT – GREGORY ANDERSON
Greg thanked everyone for their patience as we worked through the new RFID check in process.
Greg mentioned that the committee funds are in very good shape. He indicated that we have a ridiculously
low registration fee and that there is tremendous value in what is gotten for that fee.
Greg asked that meeting minutes include the date and time, attendance, and whether you plan to meet at the
next meeting. It is needed for him to plan the schedule and room size for the next meeting.
Greg did a quick overview of the committee funds status.
The finances of the Committee are in good condition. As of 31st of August 2015 (end of this reporting period), the
balance was $53,501.80.
FYI: August 31st is essentially a "snap-shot" in time after all income & expenses are resolved from the previous San
Antonio Meeting, and before we start spending significant funds for the Memphis Meeting.
No significant assets (PC projectors, etc.) were purchased during this reporting period.
The loss incurred at the San Antonio Meeting (loss of $29,682), vs. the gain at the previous DC Meeting (gain of
$28,702) was primarily due to difference in costs between the two hotel brands; i.e., the Hyatt Regency in San
Antonio, vs. the Sheraton in DC. We also incurred an expense of ~$10,000 for RFID technology at the San Antonio
Meeting.
See attached summary of the balance of this reporting period, and the previous periods.

9.0 RECOGNITION AND AWARDS REPORT – BILL CHIU
The Awards will be presented at the Tuesday Awards Luncheon. No report was made at the Monday
General Session.
NO REPORT SUBMITTED
10.0 ADMINISTRATIVE SUBCOMMITTEE MEETING REPORT
Don indicated that it is important that the work we do is documented. He indicated that we need to
record the why we chose to do something or not do something as we develop our standards and guides.
The WG is being requested to provide a short summary of the decisions.
A question was asked whether this change would be documented in the Operations Manual. Don
responded that yes it would be added.
Don also mentioned that there needs to be a better editorial review of documents prior to there going to
ballot. Also, he indicated that if you join a ballot pool, you need to read the document and provided
comments if you find grammatical, spelling, punctuation errors as well as items that are not technically
correct. He provided examples of recent documents that had errors that were not caught prior to
publication.
Don also talked about Ballot Resolution Groups (BRG). He asked if that is treated any differently than
appointment of a task force (TF). TFs are required to report back to the Subcommittee or Working
Group that they are under. He indicated that the work done by the BRG should be no different. The WG
should have the opportunity to review any majer technical comments or changes made as a result of
comments received.
10.1 Introduction of Members and Guestse
The attendees were asked to introduce themselves. The chair asked each attendee to state his/her

10.4 Chair’s Report – Donald Platts
Refer to Section 5.0 for a complete “Chair’s Report.”
Highlights:
Don mentioned that we need to use the term submersible instead of underground transformers.
He asked for contact information for the changes to include solid state transformers into our
Committee. No information from SA has yet been provided. Until more information is
provided, no further actions for integration of these type transformers will be made.
Looking for opportunities to coordinate with DOE.
Don indicated that the officers met this morning and topics from that meeting will be brought up
during New Business.
Don mentioned that he needs some help with succession planning from the SC Chairs. He
mentioned that we are also looking for a Vice Chair for Meetings Planning SC and as a back-up
for the website.
Don mentioned that an email was sent to PES indicating that PES does not acknowledge the
Transformers Committee Meeting. As a result, the technical committee meetings are now
identified on the PES website.
Don announced that Bruce Forsyth will be taking on the role of Committee Secretary January 1,
2016 and Tim Holdway will take over the role of Standards Coordinator January 1, 2016.
10.5 Vice Chair’s Report – Stephen Antosz
Refer to Section 6.0 for a complete “Vice Chair’s Report.”
Highlights:
Steve mentioned that he is looking for reviewers of approximately 14 papers for the T&D
Conference in May. He indicated that the deadline for paper submissions for the General
Meeting is fast approaching and he will need reviewers for those as well.
A panel session will be sponsored at the 2016 General Meeting on Transformer Security.
10.6 Secretary’s Report – Susan McNelly
Refer to Section 7.0 for a complete “Secretary’s Report.”
Highlights:
There were eighteen applications for membership received. Sixteen had the required memberships and
met the application requirements. Two were missing information or had missing memberships . The
application from Vijay B. Tendulkar was discussed and Casey Ballard indicated that he has been active
in the Dry-Type SC and that the missing SC Chair sign-off could be provided. There were a couple of
applications listing less than the required 2 year participation. Administrative SC members came
forward for each of these and verified that those people had been active in various WG for at least the
required 2 year period. It was noted that the Secretary Report did not indicate a SC Chair signature for
Sukhdev S. Walia. However, this had been verified and was not corrected prior to submittal of the
report.
Therefore, only 1 application , that from Shamaun Hakim, will be rejected and will be re-reviewed once
the required memberships have been provided. The remaining 17 applications were approved.
In addition to the above, a request for reinstatement to Committee Member from Past Committee
Member, Scott Reed was received. There were no objections to this reinstatement.
There were six positive responses to the essential patent claim question on the registration form. Of
those, only three provided any further detail and were noted in the full report.

10.11 Meeting Planning Report – Gregory Anderson
No written report provided.
Highlights:
Greg asked that SC/WG/TF minutes include the date and time of the meeting (not just time), number of
attendees (members & guests), and whether or not the group will be meeting at the next meeting.
There was considerable discussion regarding recording attendance at each SC/WG/TF. There is a list of
everyone that registered for the meeting with their affiliations at the beginning of the main meeting
minutes. Further information and direction will be provided on what will be required to be included in
the minutes for each group and what can be provided in AMS. Keeping attendance information in the
AMS will be required and SC Chairs should make sure that WGs and TFs under their SC are doing so.
Craig Swinderman, from Mitsubishi , host for the Memphis meeting talked about the meeting so far.
Alan Traut from Power Parners, Inc. gave a brief synopsis of the meeting that will be held in Atlanta in
March of 2016.
Greg indicated he is still working on the Fall 2016 meeting location and date.
Greg also did a demo of the RFID technology that will be in place for the Memphis meeting and
discussed the plan for expanding this at future meetings to provide real time quorum information.
10.12 Old Business
WG Data Confidentiality – E. Spiewak
Erin indicated that she talked to Rick Ladroga and the spreadsheet for data information that was
previously provided was still valid. Erin indicated that they would need to know what queries would be
needed and what fields could under no circumstances could not be included in any of the queries.
The non-disclosure agreement will still be used, and depending on what information is requested, a
second non-disclosure may be necessary.
The database will likely be done using Microsoft Access.
10.13 New Business
Draft Transformers Committee Operation Manual – Peter Balma
Don indicated that a draft of this was sent out recently. After review of this, Don indicated he felt
there were several items within the document that need to be updated and for the AdCom members to
review the entire document and review the SC Scope at their SC meeting if needed.
Don indicated the process of building a standard needs to be included in the P&P and eliminate the
overlap. This may mean that reapproval of the documents in the next year will be necessary. The
documents will then be posted on the website as reference to the members.
Topics from Officers Meeting
1. Documenting what goes into our standards and why it is there or why it was changed.
Don indicated that documentation of why something was changed, what options were looked at
and why it was changed be provided. This companion document /report of this information
would then be provided with the document sent to ballot and for future reference. Don indicated
that he would be making this recommendation at the Monday General Session. This information
would be provided to the SC when the document is brought forward for approval at the SC and
to be included in information provided with ballot.
2. Ballot Resolution Groups (BRG)
Is the appointment of a BRG different from the process of appointing a TF to look at an issue.
Does or should the WG have an opportunity to review the resolution to ballot comments? Erin
indicated that the proper procedure would be for the ballot resolution to be reviewed and
approved by the WG prior to recirculation. Also, the BRG should be a balanced representation of
the WG to avoid any appearance of collusion.
Erin indicated that the meeting minutes need to document the people that will make up the BRG
and that it be open to anyone that is interested in participating.
Don indicated that based on the discussion, there appears to be a procedural issue that needs to be
resolved on how this process should be done.
There were comments that some of the SCs schedule documents to go out to ballot a year prior to
it expiring so that they have at least two meetings for ballot resolution.
A question was asked of Erin on whether it is a requirement that only a clean copy be provided on
the first ballot of a document. The concern is that with limited time available to review
documents, knowing what was changed in a document would be very helpful to balloters.
3. WG Editorial Review
Don indicated it would be helpful to clean up many of the editorial issues prior to a document
going out to ballot. It would help reduce the number of editorial comments that need to be
resolved after a document goes out for ballot if this review is done by the WG ahead of time.
Another option raised would be to have a group responsible for an Editorial review. Erin
indicated the MEC is not a grammatical review, it is a style and legal review only.
Erin indicated that IEEE follows the Chicago Manuals Style, which dictates things like the use of
dashes, etc.
There was considerable discussion the best way to have a better grammatical/punctuation/
sentence structure review done on documents prior to them going out to ballot.
It was suggested that we make the WGs aware that the MEC does not do this type of document
review and that they are responsible for looking at the grammatical, spelling, etc.
4. Transformers Committee CD of Standards
A question was asked whether a new CD would be made available. Don indicated that one was
made available this year, but at a much higher cost than what had previously been provided. It
was discussed that maybe a compiled CD could be provided with the recently approved Standard
at the Spring 2016 Meeting.
10.14 Subcommittee Reports
Subcommittee Report/Hot Topic
Bushings – P. Zhao, reported by Eric
Weatherbee
The recently formed Task Force that was assigned to
look at Composite Bushings, with the help of Doble
Engineering sent out a survey to determine what the
current definition of composite bushing is within the
industry. The results will be discussed during the
Tuesday morning. The TF is also looking at all the
bushing standards to see if they adequately address the
recent technologies that have been brought to the
marketplace.
Dielectric Test – M. Franchek New task force on limits for winding insulation power
factor and resistance will be meeting in Memphis.
WG C57.138 Revision of impulse test for distribution
transformers will not meet, document is in ballot.
Distribution Transformers – S. Shull Nothing to report.
Dry Type Transformers – R. Ballard for
C. Johnson
C57.12.60 is starting up as a WG to revise the dry-type
insulation system thermal aging document
C57.12.50/51 are being combined to reduce future
maintenance as they were both old ANSI documents that
had the copyright given to IEEE.
C57.124 –technical experts in partial discharge are
needed to help us out on this dry-type transformer partial
discharge guide. Relevant experience with the testing
equipment is where there is a severe lacking of
information with the current SC participation. A WG
Subcommittee Report/Hot Topic chair for this activity is also being sought.
HVDC – M. Sharp The only active working group reporting to the HVDC
Converter Transformers and Smoothing Reactors
subcommittee has created a first draft for a dual logo
standard, 60076-57-129, for HVDC converter
reactors. The details will be reviewed at the SC
meeting. A volunteer to chair a working group to
update IEEE 1277 for HVDC Smoothing Reactors is
needed.
Instrument Transformers – R. McTaggart C57.13 has not yet been submitted, C57. 13.7 is ready
to go to ballot after SC approval, and at least one
standard will be discussed to start a new WG for
revision (C57.13.5).
Insulating Fluids – D. Wallach There are four WG documents wrapping up this year
and are either published or on the December
REVCOM agenda. A look ahead will be done to see
which documents might need to begin revision
cycle. Also David brought up a question about a
gentleman from Uruguay seeking opinions on
transformer DGAs. ADCOM members confirmed
that we cannot provide any sort of consulting. If
volunteers were asked to comment back rather than
IEEE, it could be seen as commercial activity. David
will send a reply noting we cannot support his request
and suggest he refer to IEEE C57.104
Insulation Life – B. Forsyth The WG for PC57.162 is meeting to continue
development of the new Guide for Moisture in
Insulation Systems. There are currently nine task forces
working and a tenth will be introduced at this week’s
meeting.
At the last meeting a task force was established to
prepare a scope for a guide for Winding Temperature
Indicators. After several meetings, the TF is
recommending expanding the scope to cover the more
general topic of temperature measurements. The TF
Chair (David Wallach) will present the proposal during
the SC meeting on Wednesday.
Performance Characteristics – E.
teNyenhuis
New WG chair for C57.120 is Rogerio Verdolin
2015 PAR is C57.32 and this is now with Revcom
2016 PAR’s are C58.158, P600076-16, C57.120 and
C57.159 – they are on track
Sheldon Kennedy will be Chair to restart C57.18.10
(first meeting is in Memphis)
New TF on Short circuit current criteria – Chair will be
David Buckmaster
Power Transformers – J. Watson Nothing new to report.
Standards SC – W. Bartley The C57.12.00 and C57.12.90 have been submitted to
REVCOM. C57.12.70 will need a corrigenda to
correct an issue found. The GMD guide C57.160 was
approved. The comparison between IEC and IEEE
has been moved to the protected portion of the web.
Underground Transformers & Network
Protector – D. Mulkey
Some interest has been expressed in reactivating
C57.12.57 – Dry Type Network Transformer working
group, however the people most interested could not
get approval to attend this meeting.

Two significant changes in favor of paper continue to be practice.
Firstly, on first submission three reviewers are required compared to earlier practice of four.
Secondly, IEEE overall has changed its policy to allow for up to 40% commonality in comparison to earlier
publication.
The first step has made the process faster while the second step allows authors to convert their ideas faster
into papers.
It is important for all interested individuals to follow the norm for writing papers as provided in IEEE; the
link is http://www.ieee.org/publications_standards/publications/authors/authors_journals.html and the link to
upload the paper is http://mchelp.manuscriptcentral.com/gethelpnow/training/author/.
I would like to thank all of the reviewers who volunteered for this effort and donated their time, and would
like to encourage everyone associated with IEEE Transformers Committee activities to consider becoming a
Reviewer. I would like to encourage those Reviewers that already have an account on IEEE Manuscript
Central to keep their profile information updated and complete the areas for key words and areas of interest.
We need more reviewers and I encourage any of you that have not signed up as reviewers to sign up per the
instructions at the end of this document.
Please inform me at [email protected] as soon as you do sign up so that we are able to utilize your
efforts as reviewer.
I would also like to take this opportunity to personally acknowledge the reviewers involved in the
transformer committee who have been regularly and consistently reviewing papers. This is an
important contribution since it maintains the high standards for our papers and it gives back to the
industry their expert knowledge.
Special mention must also go out to the editors who have worked hard to make this possible; they are Dr
Kulkarni, Dr. Francisco De Leon, and Dr. Wilsun Xu.

THURSDAY GENERAL SESSION
16.0 CHAIR’S REMARKS AND ANNOUNCEMENTS
Don introduced a topic for discussion that there has been a filing with FERC challenging the
technical content of the GMD Guide. There is no quorum to make any decisions at this meeting, a
separate request will be sent out in the coming week to the Committee Members regarding a
response on the filing.
The authors of the Docket made the following statements to FERC:
“The results presented in the IEEE Guide are a false and misleading narrative of the potential
vulnerability to EHV transformers that are exposed to GIC flows”
“The new IEEE Guide makes serious errors and underestimates in the two heating related
behaviors of transformers exposed to GIC. It even erroneously reports actual measurements
from transformer tests conducted by various parties, making them lower than actually
observed.”
Gary Hoffman, the Vice Chair of the C57.163 working group, provided some background on the
issue. He indicated that the IEEE Stds development and ballot process is consensus driven,
balanced, fair and open to all with a material interest. He also indicated that the authors of the
docket chose not to participate in the standards development process or balloting for C57.163.
A statement from individuals of the C57.163 WG, with the assistance and review of the IEEE staff,
has been drafted to explain the errors that the docket authors made. A 2/3 majority vote to send this
statement on behalf of the Committee is needed.
Don indicated that due to not having a quorum at the Thursday meeting, a separate electronic vote
will be necessary. Don indicated that he would be sending full information after the meeting
requesting review and a vote to either approve or disapprove the Committee position statement. If
members choose to vote “Disapprove”, they are requested to please provide an explanation of the
changes required before they would agree to change their vote. A 2/3 majority approval will be
required before a response to the docket can be submitted from the Transformers Committee.
The response that will be sent to the Committee Members for consideration will be as follows:
The Transformers Committee is one of the largest and most active of the 16 technical committees
of the Institute of Electrical and Electronic Engineers (IEEE) Power and Energy Society (PES).
The Committee is comprised of technical and managerial representatives from manufacturers,
consultants, vendors, and endusers of electrical transformers and components. The continuing
scope of the Committee is to develop and update standards and guidelines for the design, testing,
repair, installation, operation, and maintenance of transformers, reactors, and associated
components that are used within the electric utility and industrial power systems. One of the
Committee's responsibilities is to produce and maintain documents contained in the IEEE C57
Standards Collection.
The Transformers Committee was the sole Sponsor for the development of IEEE C57.163, Guide
for Establishing Power Transformer Capability while under Geomagnetic Disturbances. The
Working Group followed the Working Group Policy & Procedures for standards development, and
was guided by the five principles of IEEE-Standards Association: due process, openness,
consensus, balance and right of appeal.
Following these principles ensured fairness and good standards practice throughout the
development of C57.163.
The C57.163 Working Group was an open group where all materially interested parties had the
opportunity to participate. The Working Group worked collaboratively to reach consensus in
order to move the project to IEEE-SA Sponsor Ballot. The IEEE-SA Sponsor ballot consisted of a
balanced ballot group made up of a variety of interest classifications such as users,
manufacturers, producers, etc. The Guide had 130 balloters with all 285 comments resolved and a
94% approval rating. Once this consensus was achieved from the balloting process, the document
was submitted to IEEE-Standards Associations (SA) for final review and approval. C57.163 was
approved by the IEEE Standards Association Standards Board on September 3, 2015.
Upon publication of IEEE C57.163, a FERC filing (RM15-11-000) was made by Messrs.
Kappenman and Birnbach. Below are the three errors that the authors of the Docket made in this
filing:
1. When the authors of the Docket compared current harmonics and temperatures in different
graphs of the Guide, they apparently did not know that transformers of different designs can
have very different magnitudes of response to the same level of Geomagnetic Induced
Current (GIC). The Guide actually demonstrated this fact in a number of Figures and
included text on the design parameters that cause this variability.
2. When the authors of the Docket compared temperatures presented in Figure 7 of the Guide
(Figure 11 of the Docket), to those in Figure 8 of the Guide (Figure 12 of the Docket), they
did not realize that they were comparing one that showed temperatures of Tie – Plates with
the one which showed temperatures of top Yoke – Clamps. These transformer components
respond differently to the same GIC.
3. When the authors of the Docket compared the temperatures of a Tie-Plate from Figure 13 in
the Guide to those presented in the reference paper B33, they did not know that the paper
has temperatures measured at the middle of the Tie–Plate while Figure 13 has temperatures
measured at the top end of the Tie–Plate. Transformers in operation (under load) have their
highest tie plate hot spot temperatures at the top end of the tie plates; caused by the much
higher top oil temperatures.
In conclusion the IEEE Power and Energy Society Transformers Committee stands by the
technical content of the Guide as published.
Don indicated that a link to the FERC filing will be included in the information sent for review.
A question was asked regarding what authority or position the authors of the docket were testifying
for.
Gary indicated that there are two phases of the FERC order. One phase is already approved by the
sstandards commission, which is basically an outline of procedures by utilities. The second phase
was a standard for the mitigation and assessment TPL007-1. The docket objects to the second phase
because the authors don’t feel TPL007-1 fits the narrative provided in the Spectrum article that they
wrote.
Don indicated that due to time limitations, the liaison reports may not be able to be presented. He
indicated that they would all be posted as well as included in the minutes and that if time permitted,
would fit in as many as possible before time runs out.
17.0 MEETINGS PLANNING SC MINUTES & REPORT – GREGORY ANDERSON
Greg welcomed everyone to Memphis and introduced the meeting host for the Memphis Meeting Craig
Swinderman. Greg asked everyone to give them a hand. Craig thanked everyone for attending and indicated
it was an honor and privilege to be a host of this meeting. Craig introduced and thanked the members of his
team.
Greg provided meeting attendance numbers for the Memphis meeting. He indicated that this is by far the
largest meeting so far. There were 579 attendees (591 registered) and 70 spouse/companions.
Greg introduced Alan Traut from Power Partners, Inc. the meeting host for the next meeting in Atlanta,
Georgia on March 20-24, 2016. Greg indicated that the link for the hotel would be available in the next day
or two.
Greg indicated that a lot of effort goes into planning the meetings and working around other industry events
and meetings and that they are not always successful in not conflicting with other events.
He indicated that he is looking for locations for future meetings, but that we have outgrown many venues.
Greg indicated that Tom Prevost is looking for tutorial subjects and that Joe Watson was taking over
organization of the meeting break sponsorships.
Greg thanked David Wallach for his work on the meeting APP, Sue McNelly for her work on the web, Craig
Stiegemeier for help with the routers. He indicated he is looking for help with the projectors and the new
RFID device set-up.

18.0 REPORTS FROM TECHNICAL SUBCOMMITTEES (DECISIONS MADE DURING THE WEEK)
Reports from each Technical SC were presented. Their minutes are included in full in the attached Annexes.
18.1 INSULATION LIFE SC:
Bruce Forsyth presented:
Bruce announced the changeover in SC leadership with Sheldon Kennedy taking over as SC Chair as Bruce moves
up into the Committee Secretary position starting January 1. He indicated that there is a lot of activity going on in
the moisture insulation systemsWG and that they had a good meeting.
18.2 PERFORMANCE CHARACTERISTICS SC:
Ed tNyenhuis presented:
There are 15 TF and WGs. One WG has its PAR expire in 2015, C57.32, which is in good shape. There are 4
PARs expiring in 2016, C57.159 and P60076-16, which are both in good shape. C57.158 and C57.120 will need to
go to ballot and are on a fast track for approval by the end of next year. Further out for 2018 and 2019, there are 5
standards that are in good shape at this time.
18.3 POWER TRANSFORMERS SC:
Joe Watson presented:
Joe indicated that they had a quorum with 73 members present. The joint IEEE/IEC 60076-57-1202 is in ballot
discussion. C57.12.10 met and work is in progress. A motion was made and approved to return DETCs as a
standard requirement when no LTC is specified. Work on C57.93 is in progress. C57.131 and IEC 60214-1 have
been very active and having joint IEC meetings outside the country. PC57.140 is in progress. C57.148 did not
meet but will be making the first revision to this guide starting in Atlanta. C57.150 will be starting up next year
either in the spring or at the fall meeting. C57.157 has been going on for a long time and has finally been
published.
There was a motion made to work together on a joint TF with the Distribution and Standards SC on a definition of a
power transformer versus distribution transformers particularly in the area of renewable transformers. This was
approved and they awill be working together on this topic.
18.4 UNDERGROUND TRANS & NETWORK PROTECTORS SC:
Dan Mulkey presented:
The SC has 4 WG. C57.12.23 is working on updating the sizes to a 250kVA single-phase submersible. C57.12.24
has Draft 5 in ballot and a PAR extention is in the works. C57.12.40 is adding an annex about bushings and how
they are affected by short circuit currents for switches installed in most network transformers and is adding
stainless steel thickness to the copper bearing steel. C57.12.44 is starting a new revision and Bill Wimmer is
stepping down as Chair and Mark Faulkner the current Secretary has agreed to take on the role of Chair.
18.5 BUSHINGS SC:
Eric Weatherby presented for Peter Zhao:
There were 28 of 39 members and 102 guests present.
There are currently two PARs in progress for which the Chairs presented reports to the Subcommittee.
- PC57.19.01 (Standard Performance and Dimensions) expires at the end of 2017
- PC57.19.04 (GSU) expires at the end of this year; the extension request will be reviewed in the December
meeting.
It was noted that C57.19.00 (General Requirements and Test) was approved in 2004 and expires in 2020 as such it
was decided a small group will look over the standard to see if there are any obvious areas that require updating
and will report back to the SC at the Atlanta meeting. – Unfinished Business
There were two Task Force reports given to the Subcommittee.
- Distribution Transformer Bushings.
- Composite Bushings.
There were several topics discussed during the new business section of the meeting. The liveliest was brought up
by a Transformer OEM in regards to PD in bushings that occur frequently after heat run testing or other aggressive
processes. His comments were echoed by several OEM and utility personnel. There was discussion of the causes by
several bushing manufacturing people and suggestion for them to seek out the paper on Bubble Evolution at Doble.
There was also a suggestion that a section be added to the application guide and or a possible task force group
should be formed to examine the issue closely and offer a suggestion to the SC on the correct approach. – This will
be moved to unfinished business to be discussed in Atlanta.
18.6 DIELECTRIC TEST SC:
Mike Franchek presented:
There were 68 of 104 members present.
The low frequency test WG reviewed results of three surveys, the first was on tap changer position during induced
test, the second was the application of pressure inside the transformer during induced test, and the third was ground
core gassing issues on distribution transformers and proposed aproposed new design tests. All three had positive
results but there were negatives on them that will reviewed and the documents will be resurveyed before the next
meeting.
As new business, a proposal for an althernative method of performing the applied voltage test. This will be
circulated as a survey before the next meeting. The revision of impulse test survey results on impulse test front
time test parameters and tolerances were presented. The approval rate was 83% but there was a negative. In order
to resolve the negative, it was agreed to add an informative note saying that the determination of the impulse
waveshape paramaters shall be based on the test voltage curve.
Also as new business, a proposal for a new way to measure the chop wave climb during the chopped wave test was
discussed. This will be surveyed before the next meeting.
A brand new TF on winding power factor and insulation resistance met for the first time and was well attended and
covered different sections of different standards.
There was discussion on changes to the SC scope. The Chair will frame the scope and survey the members.
18.7 DISTRIBUTION TRANSFORMERS SC:
Steve Shull presented:
There was a quorum.
C57.12.20 current PAR expires at the end of next year. C57.28, 29, 30, 31, & 32, all but 32 are inactive. C57.12.34
is approved. C57.12.36 has balloted and the WG is working to resolve ballot comments. A recirculation is planned,
however because the PAR expires at the end of this year, a PAR extention will be requested. C57.12.37 has been
approved. C57.12.38 WG will apply for a corrigendum to add back in an omitted note above the bushing height
dimension stating 167kVA and 250kVA above that was found after approval. C57.12.39 expires at the end of
2016. A motion was approved to move the latest draft forward for SC approval.
60076-57-15 Draft 1.2 was approved by the WG to be sent to the SC for approval to ballot.
18.8 DRY TYPE TRANSFORMERS SC:
Casey Ballard for Charles Johnson presented:
There were or will be four PARs submitted for approval and for meetings to start at the Atlanta meeting
(C57.12.01, C57.12.91, C57.124, and C57.16).
C57.12.59 did not meet. C57.12.58 had a TF put together to review and felt it was in good shape. C57.94 is
through balloting and will wrap up shortly.
18.9 HVDC CONVERTER TRANSFORMERS SC:
Mark Sharp presented:
There were 13 members and 15 guests present.
There was only one WG that met. 61378-57-129 provided a summary of the work done at the last meeting. The
PAR expires the end of 2018.
18.10 INSTRUMENT TRANSFORMERS SC:
Ross McTaggart presented:
The C57.13 was balloted and sent to REVCOM. C57.13.7 was voted to go to Sponsor ballot. C57.13.8 is
progressing well and expects to have a 3rd
draft before the spring meeting. The CVT standard being transferred
from PSCC is expected to have a TF meet at the Atlanta meeting. A decision was made to start a WG for C57.13.5
and it will have a PAR filed prior to the spring meeting. A discussion on C57.13.2 (conformance teston instrument
CTs) was held and needs work to start on this soon, but first a determination needs to be made on whether it is still
needed.
18.11 INSULATING FLUIDS SC:
David Wallach presented:
There were 28 members and 48 guests present. A quorum was achieved.
C57.104 – Confidentiality agreements has continued to delay progress on the document. The PAR expires at the
end of 2017.
The following documents balloted this year and are on the Dec 2015 REVCOM agenda: C57.106 & C57.139. The
following two documents were published this year: C57.130 and C57.637. C57.147 revision is nearing completion
and the latest draft received approval to go to ballot from the WG and SC.
The TF for consolidation of oil guides met and a lot of work to develop conceptual table of limits combined into
one table. A PAR is expected to be developed soon.
The Particle Count TF stopped for a while, but a draft TF report has been developed and will be sent to members
for review. Afterwhich, it will be filed on the website.

No Meeting was held. Mr. Ellis reviewed the standard and did not find anything in need of updating but
asked the group to review and send him anything they deemed necessary to be brought up for
discussion as a possible revision.
The Chair noted that the revision due date for this standard is fast approaching and thought it to be
prudent to form a volunteer group to review the standard in its current form for any areas that could use
updating and report back their findings at the next meeting. Several people volunteered for the task:
Mr. Dave Geibel, Mr. Shibao Zhang, Mr. Jim Blackmon and Mr. Wes Knuth.
A.2.2 WG PC57.19.01-2000 – Dr. Shibao Zhang, Chair; David Wallach, Secretary
See complete minutes in Appendix C of this report.
A.2.3 C57.19.100-2012 – Tommy Spitzer, Chair (not present)
The guide was approved December 2012, as such no meeting was held.

A.2.4 WG PC57.19.04 – Scott Digby, Chair; JD Brafa, Vice Chair; Secretary, Jim Campbell
See complete minutes in Appendix D of this report.
A.2.5 IEC/IEEE 65700.19.03 – Les Rechsiedler (IEEE) and John Graham (IEC), Co-Chairs
The first dual logo standard was approved June of 2014, as such no meeting was held.
A.2.6 TF Distribution Transformer Bushings – Steven Shull, Chair; Ed Smith, Vice Chair
See complete minutes in Appendix E of this report.
A.2.7 TF Composite Bushings – John Graham, Chair (absent); Mark Rivers, acting Chair
Mr. Rivers showed a summary presentation of the survey that was sent out to the industry and which
was discussed in full during the TF meeting (82 attendees). The survey was provided through Doble
Engineering, which attempted to establish what the industry feels a composite bushing is and if the
current definition should be revised. He informed the subcommittee that the taskforce agrees the
definition needs to be updated but has not reached a consensus as to what the new definition should
be. He also informed the subcommittee that the taskforce concluded that the C57.19 family of
standards does not adequately cover emerging bushing technologies.
Out of 67 responses to the survey, 40% considered a Composite Bushing to have a “Non-ceramic
weathershed regardless of core insulation” and an additional 35% defined it as being any bushing with
a “Non-ceramic weathershed with solid dielectric core insulation”.
A.3 External Liaison Reports
A.3.1 IEC Bushing Standards Activity – John Graham (absent), IEEE Liaison
See complete minutes in Appendix F of this report. As Mr. Graham was unable to attend this
conference his submitted report was displayed for the group to read. Mr. Les Recksiedler agreed to act
as backup for Mr. Graham if the need arises in future meetings.
A.3.2 IEEE 693 – Eric Weatherbee, IEEE Liaison
Mr. Weatherbee gave a brief presentation/update to the group. Some points were as follows:
1) The plan to change to dynamic FEA analysis only as a requirement for transformers was removed
and will stay as a static analysis in this revision.
2) Shifting of the RRS to incorporate the natural frequency on the bushing will be required.
3) Bushings must include the addition of conductor load interactions through either MAF (moment
amplification factor) or ETF (equivalent terminal force) methods.
4) Tuned table pulse test was added for all shake table tested composites before/after the shake table
test.
5) Grandfathering of bushings is still in review.
Next meeting was scheduled to take place in Pomona, CA Dec. 2-3, 2015. Anticipated Ballot will take
place in the first quarter of 2016.
A.3.3 WG PC57.160 Guide for PD Meas. in Bushings and Inst. Trans. – Thang Hochanh, Chair

A.5 New Business
A.5.1 Partial discharge in bushings
Mr. Ajith Varghese brought up his concerns of bushing PD after heat run testing and even for new
bushings without heat run testing that is occurring more frequently. This started a long discussion with
transformer OEM’s and Utility personnel echoing his concerns. Some of the comments during the
discussion are as follows:
1) Mr. Mike Sparlok and Mr. Kumar Mani agreed with Mr. Varghese concerns.
2) Mr. Les Recksiedler said they no longer accept bushings that have this issue.
3) Ms. Susan McNelly said they have concerns with venting during testing. They worry it will void their
warranty. She suggested a section be added to the bushing application guide.
4) Mr. Harold Moore shared some history on the issue and how it occurs. He stated when
Westinghouse purchased GE bushing designs they switched from the metal can top design to
glass bowl design which has better oil viewing but causes more PD problems.
5) Mr. Dave Geibel offered up several comments including the following:
It’s been a problem forever in OIP bushings; they can obtain a paper on bubble evolution from
Doble that goes into more detail. There have been no known in service failures due to this
phenomenon. His company discourages venting as a solution as they feel it can exasperate the
problem which also can happen when taking oil samples from bushings. It does occur in bushings
that do not use glass sight glasses such as GSU designs and metal top designs. Small gas spaces
can aggravate the issue. He also shared that their company has done extensive testing and found
no problems occur due to this phenomenon.
6) Mr. Kushal Singh commented that it appears to be more of an issue in recent years.
7) Mr. Craig Stiegemeier stated that it may appear that it occurs more frequently today due to higher
sensitivity of today’s test equipment and also because transformer OEM’s have sped up their
processes. He commented that any aggressive test done by the transformer OEM can cause
bubble evolution to occur and it is not just limited to heat run testing. He suggested RIP bushing
designs could offer an alternative solution to avoid this phenomenon.
8) JD Brafa reminded the group that PD could be caused by more serious issues besides bubble
evolution as has been so far discussed. Mr. Brafa thought that it would be wise to form a group at
the next meeting to investigate this issue more closely which could then provide suggestions to
subcommittee on how the industry should deal with this phenomenon.
A.5.2 Dielectric temperature correction factor for newer RIP bushing designs
Mr. Marek Kronowski brought up a concern that he has issues when field testing the newer RIP
bushing designs as he believes the temperature correction provided by one manufacturer is not correct
for the newer bushings in its old software. Mr. Mario Larcano stated that this is a testing issue as the
test values obtained must be reviewed to verify they make sense and are not being impacted by poor
test methods or contamination etc...
A.5.3 Transformer OEMs providing CTs that fit only the bushing currently being used
Mr. Dave Geibel brought up the issue of Transformer OEMs making CTs to each bushing size (e.g.,
smaller diameter than specified in the standard). This causes issues for the end users when
replacements are needed. Mr. Keith Ellis pointed out that it states in the standard that the CTs are to
be made to accept the largest bushing designs allowed but the OEMs are refusing to follow it. Mr.
Geibel stated that it is an important issue that needs more exposure to hopefully put an end to this
practice.

Annex B
Page 4 of 14
Minutes of the San Antonio, Texas, meeting were approved, as written, by all members present at the
meeting. The motion for approval of San Antonio meeting minutes was made by Mr. T. H. Ansari and
seconded by Mr. Y. Shirasaka.
The first item of business was related to a survey on the impulse front time test parameters and tolerances.
This survey was sent on October 22, 2014 to the WG membership and to the Dielectric Tests
Subcommittee membership. Out of 531 individuals who were asked to participate, only 66 provided a
reply (return rate of 12.4%). Out of these 66, 55 were approved or approved with comments (83%
approval rate), 3 disapproved and 8 abstained. The negatives were discussed and two were rejected. In
order to resolve the third negative, it was agreed upon to add an informative note saying that
determination of the impulse wave-shape parameters shall be made on the test voltage curve after having
processed the recorded curve by the voltage function. A motion to add the following note was made by
Mr. B. Poulin and seconded by Mr. J. McBride. "Note: As required by IEEE Std. 4-2013, the impulse
wave-shape parameters such as peak voltage, front time and tail time are determined on the test voltage
curve which is obtained after having processed the recorded curve by the voltage function."
The motion has been approved by all the members present. The wording will be circulated to the WG
membership and will be voted once more at the next meeting.
As a new item of business, Mr. Ajith Varghese made a proposal regarding a new way of measuring the
chopping time during chopped wave tests. The actual wording states that the time that the voltage reaches
the zero voltage after chopping shall equal to or less than 1μs. For some winding types such as layer
windings, the wave-shape after chopping is over-damped and does not oscillate around the zero voltage
level. For such wave-shapes, the time after chopping where the wave-shape crosses the zero voltage level
can be much larger than the prescribed 1μs value. In order to solve this problem, he proposed to measure
the chopping time from the voltage value at the instant of chopping to a value which is 20% of this
voltage. This time shall be equal to or lower than 0.8μs.This will give the same intended maximum dv/dt
as the actual requirement. The WG chair will prepare a proposal that will be circulated to the WG
membership and guests prior to the next meeting and will be discussed during the next meeting.
As a new business, Mr. Mark Perkins requested to add a new item of business on the WG agenda for the
next meeting. His request was related to define a tolerance on the voltage value at the instant of chopping.
For some oscillatory wave-shapes having large overshoots, it may happen that the chopping instant
coincides when the instantaneous voltage is low (e.g. in the "valley" of the oscillation) thus reducing
considerably the stress applied to the transformer windings. The motion of adding this item of business
was made by M. Perkins and seconded by R. Verdolin. The motion was approved by all members present.
The chair will process some wave-shapes and will try to make a proposal and present some examples for
discussion at the next meeting.
The meeting adjourned at 5:45 pm on November 3, 2015. The adjournment motion was made by Mr. A.
Molden and was seconded by Mr. R. Verdolin. The motion was approved unanimously.
The next meeting is planned to be held in Atlanta, Georgia, on March 22, 2016.

B.3.5 Working Group on Revision of Low Frequency Tests
Bertrand Poulin, Chairman; Bill Griesacker, Secretary
Memphis, TN – November 3, 2015, 1:45 p.m.
1. There were 117 attendees, 25 members and 92 guests present at the meeting; 8 guests requested
membership. More than 50 % of the working group members were in attendance at the meeting,
therefore a quorum was present.
2. The agenda for the meeting was presented and unanimously approved.
3. A motion was made to approve the minutes from the spring 2015 meeting in San Antonio, TX.
The minutes were unanimously approved with no objections or comments voiced.
4. Old business
a. Applying pressure inside a transformer tank during induced test.
Survey Results: 203 ballots sent out; 134 returned 87 approve, 26 approve with
comments, 10 disapprove for an approval rate of 91.9 %.
The Chairman will review the comments with the help of members of the WG who have
volunteered for this task. The comments and negative votes can be summarized by the
two following questions:
1. Should the working group establish limits of pressure application during the PD
test?
2. Is it acceptable to use a “test” conservator that is installed in the test hall,
possibly applying higher than service pressure?
b. Tap Changer Position During Induced Test
Survey Results: Of 204 ballots sent out 134 returns, 91 approve, 27 approve with
comments, 4 disapprove, resulting in an approval rate of 96.7 %. The comments and
negative votes related to this survey were not discussed during this meeting.
Wound core gassing issue on distribution and class 1 transformers: proposed design test.
Survey results: 202 sent out, 132 returns, 82 approve, 14 approve with comments, and 14
disapprove for an approval rate of 87.3 %.
Comments will be reviewed by the Authors of the proposal. If needed, a task force will
be formed for this task. Decision to be made at the SC meeting.
5. New Business
a. Applied test for transformers with high voltage delta windings.
Annex B
Page 6 of 14
Proposal is for an alternate test method of the applied voltage test, a test applied to each
phase, which would allow use of lower voltage source so that a PD free source is easier to
achieve. The frequency of test would generally be the same as the induced voltage test
since applying voltage on LV windings and inducing two legs of core. The same voltage
as required for the Applied Voltage Test in C57.12.00 would be achieved on the HV delta
winding during this test. Motion made by Mark Perkins to vote to send out a working
group survey on the new alternate method as a replacement test for the applied voltage
test. A vote was taken and accepted unanimously to conduct the survey.
Another aspect mentioned during the meeting was the monitoring of pd during the
applied test or the new proposed alternate test on HV delta connected transformer
windings. This issue will be discussed at the next meeting.
Joe Foldi proposed to have an alternate test circuit by exciting three phases on the LV
wye winding and ground one corner of the delta winding.
b. Dielectric tests in the field. Mark Perkins will write the details of a motion to generally
require field tests on transformers with new insulation to be tested in accordance with
C57.12.00 test voltage levels and transformers with other than new insulation to be tested
in accordance with C57.12.90 test voltage levels. Background levels for PD can be a
problem in the field and will need to be addressed.
6. This working Group plans to meet next in March of 2016 at the Spring Transformer Committee
meeting to be held in Atlanta, GA.
The meeting adjourned at 3:00 p.m.

B.3.6 WG - IEEE Guide for the Detection of and Location of Acoustic Emissions from Partial
Discharges in Oil-Immersed Power Transformers and Reactors (C57.127)
Chair: Detlev Gross Chairs Vice Chair: Jack Harley Secretary: David Larochelle
Memphis, Nov 2nd 2015
Room: Grand Ballroom D
The working group met at 11:15 AM. 34 persons were in the room and 19 members were present.
Quorum requirement was met. Complete attendance record is available in the AM System.
The following guests were granted membership:
‐ Omar Ahmed
‐ Jeffrey Benach
‐ Gustavo Leal
‐ Gregorio Lobo
Discussions
The meeting started with the approval of the agenda (motion by Hemchandra Shertukde, seconded by
Michael Franchek). The minutes from San Antonio meeting were the approved (motion by Jeffrey
Benach, seconded by Omar Ahmed).
Charles Sweetser and Arturo Nunez presented their work correlating certain sources of acoustic emissions
to a frequency range. It was told that two types of sensors can be used, the first and most common being a
resonant sensor that will have a higher gain around is central frequency. The second type of sensor is
called “bandwidth” sensor. It shows a much more flat response over the frequency range but has around
3‐4 dB less sensitivity. The bandwidth sensor is well suited if FFT analysis is to be performed. It was
noted that FFT can still be performed when using resonant sensors keeping in mind that its frequency
response will affect the signal.
Questions were raised regarding the impact of hotspots and humidity on the acoustic frequency content. It
was explained that both issues would behave like PD in bubbles. Humidity will take longer to initiate PD
but will have similar features.
A question regarding the elements that trigger an acoustic inspection was raised to identify circumstances
where acoustic monitoring recommended in preventive maintenance perspective. It was told acoustic
inspections were almost always triggered by another well‐established monitoring technique (DGA for
online transformers, PD acceptance test for manufacturers). Arturo Nunez mentioned that acoustic
monitoring can sometimes be used periodically to trend a known problem in a transformer, trying to
characterize its evolution in time. If there are no technical limitations that would prevent users to use
acoustic monitoring in a permanent installation, it is not a common practice as a lot of environmental
interferences (electrical or mechanical) can affect the system. The necessity of section 5.5 (On‐line
(continuous) acoustic monitoring system) was questioned. Jack Harley then explained that concerns about
static electrification in transformers were an issue at the time were the previous revisions of the guide
were made and led to the addition of chapter 5.5. Some key transformers in power generation were
Annex B
Page 8 of 14
equipped with epoxy rods crossing the tank and connected to acoustic sensors in a permanent way. Ali
Naderian mentioned another example where permanent acoustic monitoring can be desired for nuclear
plant transformers were as much data as possible. This technique being nonintrusive (external sensors) is
seen as an advantage.
Robert Bruschetta noted that section 5.1 needed rephrasing not to exclude any possible application of
acoustic testing. Gustavo Leal asked how acoustic monitoring compares to other techniques. It was told
that DGA and electrical monitoring (from bushing for example) are preferred over acoustic monitoring.
An acoustic system could be used as a complement to these the preferred method, but is not
recommended as the only monitoring system on a transformer. Marco Tozzi suggested that section 5.5 be
modified to highlight the fact that permanent acoustic monitoring is not considered as the preferred (or
only) transformer monitoring technique.
The group will meet again in Atlanta for the spring meeting.
Adjournment
The meeting was adjourned at 12:15 PM by motion from Gregorio Lobo seconded by Arturo Nunez.

B 3.7 Working Group for PD in bushings, PTs and CTs – PC57.160
WG Secretary: Thomas Sizemore; WG Chair: Thang Hochanh
November 3, 2015 at 4:45 – Memphis, TN
The meeting of this working group was led by Thang Hochanh.
Roster sheets were circulated for attendees and guests to sign in. Interested individuals could also
indicate an interest in joining the working group on these forms. A check for a quorum was made at the
beginning of the meeting and the quorum requirements were not met with 11 members in attendance.
The minutes from the San Antonio meeting and the agenda for this meeting were presented, but due to the
lack of quorum they were not submitted to the WG for acceptation.
Thang Hochanh made a request for additional partial discharge test patterns. Andre Rottenbacher and
David Wallace indicated they could provide additional patterns for the instrument transformers.
As a means of guiding the discussion a series of comments by Pierre Riffon and the most recent draft
(5.3) were reviewed together. Most items were relatively small items but the four specific items listed
below were the main discussion points.
Item 1: Clause 4.2.2 Test circuit:
The ambient noise of ½ the maximum partial discharge limit should only be “a desirable
goal”. Nevertheless, the noise can be as high as the partial discharge limit if during the test nothing over
the noise level is observed.
Annex B
Page 9 of 14
Discussion of this point was initiated between Thang Hochanh and Pierre Riffon. An item contributed by
Detlev Gross was that the nature of the signal must be considered if the background noise is not low. The
main point of the discussion is that a test can be accepted when the stationary noise generated by the
source / environment can be clearly identified from the partial discharge coming from the test object. New
text for this section is to be proposed based on this conversation.
Item 2: Clause 6.5.1 Calibration
The calibration shall be performed within 50% and 200% of the PD limit. Replace “…at 50% and
200%...“ by “…within 50% and 200%...“
Pierre discussed what he meant in this comment. Both Dave Gibel and Thang Hochanh had several
comments to ensure that intent of this comment was clear. Pierre Riffon emphasized that a calibration at
the PD limit is the preferred level but acknowledged that in some situations this is not practical.
In résumé, the discussion cover the case were the calibrator used for the test does not have the exact pico-
coulomb limit prescribed by the test requirement.
As an example, when the partial discharge limit is 25 pC and the available calibrator does not have this
exact value, the test person can choose the value below or above the required partial discharge limit.
50% of 25 pC is 12.5 pC
200% of 25 pC is 50 pC
Usually commercial PD calibrators, have step values of 20 pC and 50 pC, in the above range.
The test person can choose 20 pC or 50 pC as the initial calibrated value.
Item 3: Clause 7.2.3 Perform a calibration of the test circuit
This is similar to the discussion of Clause 4.2.2 and will be handled similarly in this section.
The ambient noise of ½ the maximum partial discharge limit should only be “a desirable
goal”. Nevertheless, the noise can be as high as the partial discharge limit if during the test nothing over
the noise level is observed.
Item 4: Clause 7.3.1 (CT)
Often, the pre-stress level is equal to the power frequency withstand test (see IEEE C57.13.5). When
performed at 50 Hz or 60 Hz the pre-stress voltage duration is maintained for a duration a 60 seconds not
7200 cycles.
The conversation on this point focused on the difference in the required frequency for CTs and PTs.
It is necessary to take in account in this clause the frequency of the test source in order to comply with the
7200 cycles and the frequency of the source. This subject is related to applied voltage to potential
instrument transformers. When the frequency of power source is higher than 2 time the power frequency
(i.e. 60 Hz), then the duration will be less than 60 seconds. The minimum duration is still no less than 15
seconds. The 60 seconds is the maximum duration for all cases.
Example:
Power source frequency is 180 Hz. Applied duration will be 40 seconds.
Annex B
Page 10 of 14
Shibao Zhang made a proposition to remove 2 paragraphs of clause 6.2, concerning the inboard end of the
bushing in oil. It was accepted by the chairman.
The meeting was dismissed as the discussion on comments from Pierre Riffon was completed.
This WG plans to continue working at the Atlanta meeting.

Agenda presented to all attendees
Attendance: Total: 94 attendees Members: 2 Requested membership: 43 Guests: 49
1. Attendees Introductions
TF Chair – Susmitha Tarlapally (Electrical engineering manager, ABB Inc, Jefferson City, MO
Secretary – Diego Robalino (Senior Applications Engineer, Megger North America, Dallas, TX)
2. TF Chair made a presentation of the proposed scope for the TF and invited all attendees to
become members of the TF.
Proposed Scope:-
Review and determine if limits for, winding insulation power factor and insulation resistance for
power and distribution class transformers that include both mineral oil and alternate liquids, can
be established.
3. The presentation included references form IEEE Standards C57.12.00.2010, C57.12.90.2010
and C57.152.2013, where limits have not been set for PF or for Insulation resistance. It was
also pointed out that NETA has provided reference values noting that specific limits are not
given in the regulating standards.
4. The text from C57.12.90.2010- Table 4 Notes on Power Factor were discussed where
interpretation of results is based on experience and a variety of other factors.
Annex B
Page 11 of 14
5. The question put to the attendees was: What would be a typical Power Factor value to
consider before the transformer is shipped?. What is a typical number that necessitates the
manufacturer to investigate further before shipment?
6. Similar discussion was taken regarding the information provided in the standards for
interpretation of IR.
7. Presented the reference tables from NETA stating that “in absence of consensus standards, he
NETA Council suggests representative values.
8. Not having consensus in the reference standards implies as well a variety of values given by
manufacturers that will differ from factory to factory.
9. Therefore, the importance of this TF is to collect data and provide a logical, understandable
and beneficial statistical analysis.
TF Chair requested the input form the attendees and initiated an open discussion
Mark Perkins (ABB) – stated that PF is misunderstood for limits. ABB has lots of experience with DFR
and has gained more understanding now of PF. Modeling of different types of transformers considering
the parameters affecting PF are: % of cellulose material vs liquid insulation and temperature correction.
Large power transformers are about 20% - 30% paper and the oil volume may lower the PF value. Other
parameter is moisture concentrated in cellulose. Conductivity of oil, for power transformer IR is a task of
oil conductivity as direct measurement. The suggestion is to probably come up with a three-dimensional
model having PF, temperature and moisture will clarify the topic. It also need to consider type of winding
and core. Mark also proposed to include theoretical references of PF vs other parameters. Mark volunteers
to take this task.
Poorvi Patel (ABB) – questioned if this TF is only for factory acceptance values or also field?
Susmitha Tarlapally (ABB) – indicated that initially the TF will look into acceptance/factory values, but
the TF would want to stablish guidelines for service aged distribution transformers.
Evan Langran (RES) – suggested to include service life meaning chronological years in service (real
service not just reference to manufacturing date), vector diagram and service application.
Ajith Varghese (SPX) – suggested also Tap changer type, bushing type, type of insulation oil for IR and
PF, reprocessed oil vs new oil.
Donald Agers – suggested material used for the insulation winding
Peter Heinzing (Weidman) – look for materials, laminated wood, influence on PF, geometry of windings.
Paintong Yang (pens. Xmer), - coil configuration
Ali Naderian – separate the field and the factory data. Suggested to include oil tan delta
Chuck Switseer (OMICRON) – commented about the complications faced in C57.104. Data was
collected and it is proprietary. Reminded of the issues with temperature collection, PF and IR differences
between CHL vs CH and CL. He also suggested to consider the slope of power factor sweep.
Poorvi Patel – questioned is the collect data from the field should only consider units in good condition.
Robert Lobo (Mitsubishi) – Suggested to include atmospheric conditions. %HR and pressure may have an
influence

Egon Kirchenmayer (Siemens) – PF for core and windings,
The input from the attendees has been gathered. At this point the effort of the group is to collect the data
and start working on the statistical analysis.
Diego Robalino (MEGGER) indicated that there will be information that manufacturers may not be able
to share and for now we should be able to identify those particular parameters. The invitation was
extended to all attendees to volunteer and contribute with the work of this TF.
Volunteered:
Kirk Robbins (Exelon)
Evan Langran (RES)
Ajith Varghese (SPX)
Poorvi Patel (ABB)
Egon Kirchenmayer (SIEMENS)
Pugazhenthi Selvarajay (Virginia Transformers)
Jermaine Clonts (Power Partners)
Krishnamurthy Vijayan (CG Power Systems)
Vijay Tendulkar (SMITHS Power)
Gregorio Lobo (Mitsubishi)
K. Shane Smith (Delta Star)
Mike Perkins (ABB)
Michael Franchek (WEIDMANN) – dielectric Test SC Chair noted to the TF that IEEE has the ability to
manage confidential data under an established DB system. There will be confidentiality agreements to
protect the information and make sure it is secure for all participants during the process.
Wallach (Duke Energy) has records of PF in the database.
Peter Werelius – recommends an organized way to collect data, from DFR we know better the behavior of
PF as it is related to other factors. The statistical analysis should be such that a bad batch of data should
not leverage the good data and mislead the interpretation and the limits for IR or PF. Volunteer as well.
Information was collected and the meeting adjourned at 9:05

B.4 Liaison Reports
B.4.1 Voltage Test Techniques (HVTT), IEEE Standard 4 - Arthur Molden
HVTT group did not meet at Memphis.
B.5 Discussions
As a follow up of WG report of low frequency test, it was discussed and agreed in SC, that survey
comments on wound core gassing will be reviewed by Phil Hopkinson and team that originally
proposed the test and new text will be re-surveyed. Susmitha Tarlapally requested that it should
be surveyed in both DTSC and WG, which was agreed.
With respect to alternate applied voltage test method that approved to survey in WG of low
frequency test, Mr. K Vijayan ( PTI ) commented that WG approval for survey is unrelated to PD
measurement during Applied voltage test. Vijay wanted to be clear that PD measurement during
applied voltage test was not discussed in WG and it should not be linked to the survey prosing
alternate test method. Bertrand Paulin clarified that that PD measurement is a separate new items
for future discussion.
B.6 Old Business
No old Business was there for discussion
B.7 New Business
Scope definition of DTSC was brought as new items for discussion by the chair. Chair read the
current text from transformer committee manual which many members felt did not adequately
reflect the work undertaken by this subcommittee. There was lot of discussion around word “
voltage test “ included in current text with some members suggesting alternative wordings of “
Dielectric Test” , “ over voltage test” or “ Assessment test ”. It was also pointed out that reactors
are in scope but is missing in current scope statement.
A question was asked if Dry transformers are in scope of DTSC, which Chair answered in
negative.
With many suggestions and no consensus on the wording of scope, a motion was brought by
Daniel Sauer to have chair frame the text/wording incorporating comments made during
discussion and have the wording surveyed within members of DTSC. This motion was seconded
by Bertrand Paulin and was approved unanimously.
Annex B
Page 14 of 14
A separate motion was passed to establish a "Standard 4 Technical Advisory Group" as part of
Transformers Committee Meetings, as is done by our IEC TC 14 Technical Advisory Group. This would
provide a forum for our members to discussion and comment on the work being done by the HVTT
Working Group .Motion brought by Art Molden and seconded by Jim McBride was approved
unanimously.

On the chair report, Carlos informed that the PAR expired in Dec. 2016, and that there was an item in the agenda to vote to initiate a sponsor ballot process. On old business, the work of the Task Force on PRD flow rate was presented. Josh Herz said that the task force was really attempting to bring the real operating characteristics for PRDs being used in line with the wording of the standard, which had not been met for some time with the current PRDs. New wording for the PRD operating characteristics was reviewed. Dan Mulkey said that the data of PRD should not be part of definition. Al Traut questioned if by removing the data from definitions, the PRV and the PRD could be differentiated. Omar Ahmed mentioned if rupture discs should be considered on the document. After some discussion, Dan Mulkey made the motion to strike the last 3 lines of the PRD definition. Steve Shull seconded. The motion carried. Then Dan Mulkey made the motion to simplify the definition of PRV similar to the motion on PRD. Steve Shull seconded and the motion carried. Adam Bromley asked why the rapid transient test isn’t required for square tanks like pad mounts. Carlos responded that the group decided not to include these types of equipment as they have a higher mechanical capacity to absorb energy than round tank designs.
Then Draft 4 was reviewed; it included the comments to Draft 3 that were received after the Spring 2015 meeting. Al Traut made the motion to accept the changes proposed in Draft 4; Alejandro Macias seconded, and the motion was approved unanimously.

C.4 New Business
• Steve Shull presented a revision to the SC scope modifying it to include voltage regulators and address the enclosure integrity standards. Ron Stahara motioned to approve; Dan Sauer seconded and much discussion ensued with editorial considerations. After several revisions were offered as friendly amendments with some accepted and other rejected Gary Hoffman called the question. The SC approved the call with 26 in favor and 1 opposed. The motion was then voted on as amended and the motion carried with 30 in favor of the revised SC scope. The following is the final scope:
8 of 9
Annex C
The Distribution Transformers Subcommittee shall be responsible for the following: a. Studying and reviewing engineering aspects of voltage regulators,
distribution overhead, distribution pad-mounted, and distribution substation transformers. This would include enclosure integrity, and surface coatings and corrosion resistant materials as related to the enclosure.
b. Developing and maintaining related standards, recommended practices, and guides for such products
c. Coordinating with other technical committees, groups, societies, and associations as required
Steve will present this revised scope to the full committee in the closing session on Wednesday.
• Phil Hopkinson presented a need for definition of renewable transformers which he considers as step-up power transformers. Phil asked the members to consider should a renewable (step-up) transformer be a distribution or power class? Phil stated that if they are distribution transformers then the DOE could govern the efficiency while power step-up transformers are not. Dan Sauer offered that if they are power transformers they might not be tested for some useful things like impulse testing. Ron Stahara asked if the DOE rules cover power transformers and Phil said, not presently.
C.5 Chairman’s Closing Remarks and Announcements
Steve had no closing comments to the SC except to see them in Atlanta in the spring.

D.2.2 IEEE PC57.94 - WG Dry Type O&M Guide
Chair Dave Stankes
We received confirmation from Karen Evangelista at IEEE that PC57.94 (PE/TR)
Revision "Recommended Practice for Installation, Application, Operation, and Maintenance of Dry-
Type Distribution and Power Transformers" will be reviewed by RevCom at its December
2015 meeting. We are not anticipating any issues at this time, and expect the document to be approved
by the end of the year.
D.2.3 IEEE C57.12.91 - Dry Type Test Standard
Chair Derek Foster
The Task Force met in the Venetian Room of The Peabody
There were 7 members and 6 guests present, with 2 guests requesting membership. A quorum was not
reached.
The minutes of the April 14, 2015 meeting in San Antonio were reviewed and no comments were
received.
The agenda was reviewed and no comments were received.
Old business
A discussion was held on the Scope and Purpose for the new PAR. The Scope contains four
revisions from the scope in the current standard:
1. The addition of reference to the fact that this standard applies to transformers with a
voltage of 601V or higher in the highest voltage winding.
2. Removal of the word “safety”
3. The products listed as exceptions have been listed as bullet points, to be consistent with
C57.12.01
4. Two additional products have been listed as exceptions, Testing transformers and
Welding transformers.
The purpose will remain as written in the current standard.
There was unanimous agreement that the Scope and Purpose as presented should be used for the
new PAR.
There were discussions on topics for the new revision:
o Calibration requirements – This topic was raised at a previous meeting and at that time, it
was decided to see how this subject is handled in C57.12.90. No decision was reached at
this meeting, so this topic will be reviewed further at future meetings.
o Sound level measurement – The task force on sound level measurement is ongoing, so
their activities will be monitored and this subject will be reviewed at future meetings.
o Sound level measurement with full load, as a type test – Sanjib Som had suggested that
this test be added to the standard. After some discussion on the subject, Sanjib agreed to
provide a written proposal for consideration by the Working group.
Annex D
Page 4 of 8
o Monitoring of leakage current during the applied voltage test – Sanjib Som proposed that
the procedure for the applied voltage test should include monitoring of leakage current
during the test, with a tolerance set as a pass/fail criteria. Casey Ballard referred the
group to the applied voltage test procedure in C57.12.90, which could also be generally
used for C57.12.91. Sanjib agreed to make a written proposal for consideration by the
Working Group.

D.2.4 IEEE PC57.12.51 - Dry Type Product Standard “> 500kVA Ventilated”
Chair Sanjib Som
The working group met in the Venetian Room of The Peabody Memphis Hotel.
The meeting was called to order at 11:15 AM by Chairman Sanjib Som.
The meeting was convened with members (12 out of 18 – therefore a quorum was reached with
66.7% attending) and 6 guests present. The attendance will be reported in the AMS.
The minutes of the San Antonio TX April 13, 2015 meeting were approved unanimously.
Motion: Casey Ballard
Second: John K. John
The Chair announced that Tim Holdway would be stepping down as the Secretary of this WG and that
after this meeting; Mark Gromlovits has kindly consented to replace Tim.
Old business
o The Chair showed a spreadsheet of the work done by the TF of the suggestions in combining the
two documents, C57.12.50 and C57.12.51.
o There was extensive discussion which used up most of the meeting. During the discussion it was
decided that we would first take the two documents, combine them, and then the Chair will send
out the single document for the members to review and comment. The comments that were made
will be sent to the Chair once the single document is sent out.
o The Chair made a comment about taking out the kVA and voltages from the title. Casey Ballard
stated we need to leave them in due to differentiating the title from C57.12.01. No formal
proposal was made.
o Casey stated he will send to the Chair a clean, new document of the proposed C57.12.51, with the
combination of C57.12.50 and C57.12.51. He will also send the Chair a redline document of
C57.12.51 with the corrections or additions. The Chair will then send out the two documents to
the members of the WG.

D.2.5 IEEE PC57.12.60 - Dry Type Thermal Aging
Chair Casey Ballard
The task force met in the Venetian Room of the Peabody Hotel.
The meeting was called to order at 9:32 AM by Chairman Casey Ballard. Introductions were made and
attendance sheet was circulated.
The meeting was convened with 40 people in attendance. Since this was, the first meeting of the
working group 18 attendees requested membership and will be added to the roster.
The minutes from Spring 2015 TF meeting in San Antonio and agenda were approved unanimously.
The agenda was approved unanimously.
Old business
1. PAR Approval
Chair reported that the PAR that was developed at last TF meeting in San Antonio was submitted at
approved, effectively changing group status from TF to Working Group.
2. Reference Temperature Explanation – Roger Wicks
Roger Wicks reviewed information regarding the use of Thermal Endurance test procedures used to evaluate the
effect of temperature on the life of a material. The procedures, using multiple aging temperatures higher than
the expected operating temperature, allow for shorter test time periods. Test results are extrapolated to
determine the temperature at which a material can be operated for a finite amount of time, typically based on the
life requirement for the material in the electrical equipment.
A comment from regarding the use of longer duration test times by nuclear industry in order to confidently
extrapolate to long expected life times was offered. Current extrapolated reference time in C57.12.60 is 40,000
hours. Roger compared this to other extrapolation times referenced in IEC, IEEE, and UL standards ranging
from 20,000 to 180,000 hours. It was noted that as extrapolation times are increased, it is difficult to ensure that
results are statistically sound.
Question was raised regarding how IEC handles extrapolation hours. It was explained by Roger that IEC (for
medium voltage transformers) does not have an appropriated test procedure for systems tests. IEC currently
requires that the insulation materials component rating be used to assign temperature class of electrical
apparatus.
Chairman reminded the group that C57.12.60 is used to specify appropriate test methods to collect data on
system life, but that other standards will be used to interpret results and subsequent use.
Annex D
Page 6 of 8
At this time the consensus of the WG was to retain the 40,000 hour reference time
3. Full Size Working Coil – Chuck Johnson
Chairman displayed proposal by Chuck Johnson for definition of the Full Size Working Coil suitable
for testing, as this is not well defined in the standard
Page 5 Section 4.2.1.a
Small-scale transformer coils. Test samples should be actual full size working coils capable of
meeting the requirements of IEEE C57.12.01 and passing the testing per IEEE C57.12.91. Coils shall
be selected to represent the transformer range for commercial use. . . . . . . . .
Dhiru Patel asked if this definition would affect the use or description of “motorettes” which are also
specified as acceptable for testing in the standard. It was confirmed by the Chairman that it would
not affect motorettes. It was also asked what range of kVA transformer would/could the test
transformer cover, and it was explained by the chair that only voltage range would be specified.
Chair explained that the size of the small scale transformer coil must be or reasonable (practical) size
in order to move and place units in oven.
A motion to approve Chuck Johnson’s proposal as written above for definition of “full size working
coil” was made by Roger Wicks and seconded by Mark Gromlovits. The motion was carried
unanimously.
4. Accuracy of model types – Mark Raymond
As Mark Raymond was unable to attend this meeting, discussion on this topic was delayed until the
next WG meeting.
New business
1. PD Measurement as a trending test
It was suggested by chairman to consider adding partial discharge initial/trending test for full size test coils.
Initial test should ensure that all full size test coils (not motorettes) meet requirements specified in 12.01, as to
eliminate coils that may be fail prematurely due to defect unrelated to thermal degradation. Roger Wicks and
Ashley Reagan said this test for PD may be likened to dielectric proof testing of motorettes used in low voltage
system testing. The trending test results would be conducted using 1.5 x’s values listed in 12.01 for solid cast
and resin encapsulated. Trending tests would not be mandatory, and data could be mapped against “end of life”
(dielectric failure) for coils, perhaps helping users better understand PD to as it relates to life of transformer in
field.
Phil Hopkinson asked if the C57.12.60 would try to recommend appropriate test method for PD. Chairman
confirmed that the standard would instead point to appropriate test standard for test method (C57.12.01 or
C57.12.91 or C57.124)
Alexander Levin asked if it made sense to require PD test for all types of transformer types covered by this
standard. Casey stated that even OVDT with poor resin saturation, air bubbles, etc. may have problems with
PD, so yes, all types of transformers should be included in testing.
Dhiru Patel commented that because this type of testing will not be required, it should be instead listed in
Annex.
Vijay Tendulkar proposed a motion to include information relating to PD trending test as part of the Informative
Annex. Motion was seconded by Dhiru Patel and motion was carried unanimously.
Annex D
Page 7 of 8
2. Major Insulation materials and method for changes
Chairman described that 12.60 currently defines how to evaluate a new insulation system, but does not have any
direction for how to modify one.
A proposal for method to approve a major insulation substitution or thickness change in previously approved
system was made involving the use of a “single point test”. This method would compare average time to failure
of the new system and compare to data from original system.
A proposed list of major insulations materials used in MV transformers was shown. Varnishes were listed as
Major insulation, with the proposal to require single point testing for any new varnish approvals. It was
described that current method of approving new varnish uses Chemical Compatibility or “Sealed Tube” test.
(25C above system temperature class for 336 hours). An example of single point test for 220C temperature
class major insulation substitution was shown.
Dhiru Patel asked if testing would be required if a new manufacturer of a NEMA listed enamel coated
conductor is used.
Vijay reminded the groups that Cu is more chemically reactive than Al, and that this should be considered when
testing and approving/modifying a MV system.
The meeting was concluded at this point due to no more time, and chairman confirmed that information
presented during the meeting (powerpoint) would be posted on the IEEE website.
It was confirmed that the WG would meet again at the Spring 2016 Transformer Committee Meeting in Atlanta.
Meeting was adjourned at 10:45AM

Introductions were made and the attendance list circulated.
There were 13 members and 15 guests present. None of the guests requested membership
The total membership of the SC is 17. We needed at least a total of 9 members to be present in order to have a quorum. This was achieved.
The agenda for this meeting was approved
E.2 Approval of the minutes of the October 20, 2014 meeting in Washington, DC
The minutes from the San Antonio meeting (Spring 2015) were approved after a motion by Pierre Riffon and seconded by Rogerio Verdolin.
E.3 Brief report on the meeting of the Administrative SC

After the Ballot Resolution Group completes their work they must obtain confirmation from all members of the working group that any changes that they made are approved by all.
All working groups are responsible for assuring proper English grammar is used in their documents. The IEEE editorial staff do not check this.
E.4 Working Group Reports
E.4.1 WG IEC/IEEE 60076-57-129 – Ulf Radbrandt (IEEE) and Anders Lindroth (IEC), Co-Chairs
This joint workgroup has had one joint meeting since the last IEEE Transformers Committee Meeting (San Antonio, Spring 2015). That meeting was in Milan in September 10-11, 2015
The Agreements and actions from the Milan meeting were the following:
• Result from the Ballot within the IEEE SC were discussed and actions on each comment were decided.
• Chris Plötner had sent updated audible sound sections prior to the meeting. This was included to the document.
• Pierre Riffon had sent an updated clause of determination of hot-spot temperature prior to the meeting. This was included to the document.
• The over-excitation test, for which Pierre Riffon had prepared a proposal for text, was not included. The reason is that this standard should include requirements that are special for HVDC
Page 1 of 3
Annex E transformers. The intent for including it in this standard was that HVDC transformers are often very important for the AC system and that motivates more stringent testing than for ordinary ac transformers. However, it was argued that there are AC transformers that also are that important to the AC system. Users can include this test in their specifications. Eventually, this test might be included in the general transformer standards.
• An extended polarity reversal test has been introduced to the document. This is a special test that can be used for applications where there will be frequent polarity reversals in operation. The time with PD criteria is extended to any sliding 30 min window within the 2 hours following the completion of each polarity reversal. The test is divided into Alternative 1 and Alternative 2.
• Alternative 1 is extended to 6+8+2 hours. For units that are subjected to this test, the normal polarity reversal test is not necessary.
• Alternative 2 is combined with the DC applied test. The test time is 3(2+1)+8+2 hours. For units that are subjected to this test, the normal polarity reversal and the DC withstand test are not necessary.
• Eric Davis will check if there is an IEEE document corresponding to IEC 60270
• Anders Lindroth will review the list of references and delete the ones which are not referred to in the document.
• Eric Davis to check the wording in the section on use of normative references.
• Ugo Piovan to send the Word version of Annex A in IEC 61378-1 and Anders Lindroth will include it in the document as Annex F. This is a more complex and more accurate alternative way of calculating eddy losses.
• Eric Davis to review Annex C (Design Review) to cover HVDC converter transformer specific items.
• Sheila Batey to arrange the references. All bibliographies should be collected to the end of the document.
• Our ambition is to have the first CD sent out for comments within IEC and IEEE before the end of this year. To be able to achieve this, all above tasks have be completed and reported to me before the end of November.
• We are planning to ask IEC to limit the period for comments to two month. If that will be accepted, the comments will be available for discussion at the next IEEE HVDC Converter Transformers and Smoothing Reactors SC meeting in the spring of 2016.
E.5 Discussions and agreements regarding the work for a Dual Logo standard for converter transformers
Ulf Radbrandt made a presentation of the progress of the joint IEC/IEEE WG meetings (according to clause E.4 above). The discussions and agreements during and after the presentation were as follows:
• Switching Impulse Level and Test 7.3.2.2 should be rephrased to be clear that there should be switching impulse levels and tests for the valve side windings even for voltage levels that are so low so switching impulse would not be applicable for normal a.c. transformers. The reason is that switching impulse levels normally are very close to the lightning impulse levels for HVDC transformers and that requires switching impulse tests for low voltage windings (e.g. for transformer for back-to-back schemes). The standard should not include requirements on, or references to, the insulation coordination.
• Induced voltage including running of oil pumps with OD cooling. The text should be changed so that two tests (with and without pumps running) would not be mandatory. It should be open for agreement between manufacturer and purchaser to agree if the
Page 2 of 3
Annex E normal induced test can be performed with the pumps running. There was much discussion about whether or not pumps running or not is more onerous a test but no conclusions were reached
• Pierre Riffon will check if we can refer to general standards (IEC 60076-1, IEEE C57.12.00 and IEEE C57.12.10) for requirements on sections of the actual edition of C57.129 that have been excluded from the dual logo document (for example: sections dealing with oil and accessories).
• Over-excitation test The joint IEC/IEEE WG had decided not to include this test since it is not a test that specifically concerns HVDC transformers. Some people in the IEEE SC do still consider that it is good to include it in the dual logo document due to the much more severe consequences in losing one HVDC transformer compared to losing one a.c. transformer (in most cases). A voting took place among SC members and the result was 5 votes to include the test to the dual logo document and 4 votes to not include it. This question will go back to the joint WG.
• The introduced extended polarity reversal test (special test) We should include text about d.c. bushing test with the same amount of extended times. This means that if an extended test is selected then the bushings that will be mounted on the transformer, that will be subjected to this test, must be tested with polarity reversal test with the same duration as for the transformer test.
• Normal polarity reversal test The normal polarity reversal test is 90 + 90 + 45 minutes, with acceptance criteria on PD during the 30 minutes following on each polarity reversal. That means that the last 15 minutes are meaningless. Should we do anything about this? This question will go back to the joint WG. Discussed alternatives were:
• Extend the acceptance criteria to 45 minutes with the number of allowed pulses (≥ 2000pC) increased from 30 to 45.
• Extend the acceptance criteria to 45 minutes with the number of allowed pulses (≥ 2000pC) remaining at 30 but during any sliding 30 minute interval.
• Annex A “In service overloading of HVDC converter transformers”, Table A.1 The table contains limits for the increase in concentration of dissolved gases in oil during overload testing. The limits are not the same as the limits in Annex D “Dissolved gases analysis for the detection of local overheating” of IEC 60076-2. Some limits are more stringent in the dual logo document even though it is related to overload there. N.B. This is unchanged from the IEEE document. The limits should be reviewed. This question will go back to the joint WG.

The status of the various standards handled by the ITSC was reviewed. Three items in particular were
noted. First C57.13.5 needs to start the revision process. Pierre Riffon has agreed to co-chair this effort.
David Wallace indicated he is willing to act as the co-chair as well. C57.13.6 will be allowed to expire or
be withdrawn as it is now covered by the version of C57.13 now under review by RevCom. A survey
will be sent out regarding the C57.13.2. Some members questioned how heavily the standard is used. If
it is used regularly then the process to revise it should start within a year or so.

F.6.3 Working Group for Revision of IEEE C57.13 Instrument Transformers - R. McTaggart
No meeting was held – Standard is with RevCom
F.6.4 WG PD in Bushings & PTs/CTs PC57.160 - Thang Hochanh
The meeting of this working group was led by Thang Hochanh. Roster sheets were circulated for
attendees and guests to sign in. Interested individuals could also indicate an interest in joining the
working group on these forms. A check for a quorum was made at the beginning of the meeting and the
quorum requirements were not met with 11 members in attendance.
The minutes from the San Antonio meeting and the agenda for this meeting were presented, but due to
the lack of quorum they were not submitted to the WG for acceptation.
Thang Hochanh made a request for additional partial discharge test patterns. Andre Rottenbacher and
David Wallace indicated they could provide additional patterns for the instrument transformers.
As a means of guiding the discussion a series of comments by Pierre Riffon and the most recent draft
(5.3) were reviewed together. Most items were relatively small items but the four specific items listed
below were the main discussion points.
Item 1: Clause 4.2.2 Test circuit:
The ambient noise of ½ the maximum partial discharge limit should only be “a desirable goal”.
Nevertheless, the noise can be as high as the partial discharge limit if during the test nothing over the
noise level is observed.
Annex F
Page 3 of 4
Discussion of this point was initiated between Thang Hochanh and Pierre Riffon. An item contributed
by Detlev Gross was that the nature of the signal must be considered if the background noise is not low.
The main point of the discussion is that a test can be accepted when the stationary noise generated by
the source / environment can be clearly identified from the partial discharge coming from the test
object.
New text for this section is to be proposed based on this conversation.
Item 2: Clause 6.5.1 Calibration
The calibration shall be performed within 50% and 200% of the PD limit. Replace “…at 50% and
200%...“ by “…within 50% and 200%...“
Pierre discussed what he meant in this comment. Both Dave Gibel and Thang Hochanh had several
comments to ensure that intent of this comment was clear. Pierre Riffon emphasized that a calibration
at the PD limit is the preferred level but acknowledged that in some situations this is not practical.
In résumé, the discussion cover the case were the calibrator used for the test does not have the exact
pico-coulomb limit prescribed by the test requirement.
As an example, when the partial discharge limit is 25 pC and the available calibrator does not have this
exact value, the test person can choose the value below or above the required partial discharge limit.
50% of 25 pC is 12.5 pC
200% of 25 pC is 50 pC
Usually commercial PD calibrators, have step values of 20 pC and 50 pC, in the above range.
The test person can choose 20 pC or 50 pC as the initial calibrated value.
Item 3: Clause 7.2.3 Perform a calibration of the test circuit
This is similar to the discussion of Clause 4.2.2 and will be handled similarly in this section.
The ambient noise of ½ the maximum partial discharge limit should only be “a desirable goal”.
Nevertheless, the noise can be as high as the partial discharge limit if during the test nothing over the
noise level is observed.
Item 4: Clause 7.3.1 (CT)
Often, the pre-stress level is equal to the power frequency withstand test (see IEEE C57.13.5). When
performed at 50 Hz or 60 Hz the pre-stress voltage duration is maintained for a duration a 60 seconds
not 7200 cycles.
The conversation on this point focused on the difference in the required frequency for CTs and PTs.
It is necessary to take in account in this clause the frequency of the test source in order to comply with
the 7200 cycles and the frequency of the source. This subject is related to applied voltage to potential
instrument transformers. When the frequency of power source is higher than 2 time the power
frequency (i.e. 60 Hz), then the duration will be less than 60 seconds. The minimum duration is still no
less than 15 seconds. The 60 seconds is the maximum duration for all cases.
Example:
Annex F
Page 4 of 4
Power source frequency is 180 Hz. Applied duration will be 40 seconds.
Shibao Zhang made a proposition to remove 2 paragraphs of clause 6.2, concerning the inboard end of
the bushing in oil. It was accepted by the chairman.
The meeting was dismissed as the discussion on comments from Pierre Riffon was completed.
Spring meeting 2016: This WG plans to continue working at the Atlanta meeting.
F.7 Special Presentation
Eddy So created a presentation regarding the applicability of TCF/RCF in current applications. This was
presented by Adnan Rashid. Limited questions were asked and the presentation will be made available to
the members of the sub-committee. Pierre Riffon questioned if the power factors have really changed as
indicated in the presentation noting that utilities target unity power factor. Zoltan Roman noted that if the
method for determining accuracy is to change then the standard burdens need to be reviewed as well.
F.8 New Business
Ross McTaggart brought up that our sub-committee is being asked to take over a portion of the work for
the CCVT C93.1. Zoltan Roman will chair the efforts of the ITSC. This will be a joint working group.
A task force is to start work in the spring meeting.

The WG Report at the Sub-Committee Meeting: Presented by Patrick McShane:
The WG meeting was held Monday, November 2. The WG issued the second draft vote
after the S15 meeting. The post ballot resolution draft was reviewed at the F15 meeting and
Draft 2 was completed, and voted unanimously by the WG to forward for the SCIF for its
approval to move to ballot process. Also, because Draft 2 contains changes in the Draft
Title and Purpose, a PAR modification must be requested and approved. The SCIF motion
to approve forwarding the Draft to RevCom was made, seconded, and approved
unanimously. The WG goal is to achieve RevCom approval before the PAR expiration
occurs the end of 2016.

The TF Report given at the Sub-Committee Meeting by Tom Prevost:
Tom Prevost TF Chair reported: 4 current insulating liquid guides exist. Revisions
C57.111 and C57.121 have been published. Guide C57.106 is being sent to RevCom for its
December meeting approval. C57.147 on way for balloting in 2016. Once these four guides
are published and stable the TF Chair will apply for a PAR for the consolidated guide.
Several TFs have already formed including focus on reviewing suggested consolidated
value limit tables. There was discussion on the applicability for a type of insulating liquid
for each voltage class. It is an important issue that needs addressing and resolution.

G.1.5.8 TF o n Particle Co u n t Lim its in Min e ral Oil
Chair: Mark Scarborough, Secretary: Paul Boman
Mark Scarborough reported: A meeting of this TF was not held, however a draft of a
white paper has been written and recently sent to the TF members for their comments and
approval.
G.2 Old Business
The status of the TF of the Standards Sub-Committee assigned to issue a white paper one
Insulating Liquids Terms Normalization was reported by the TF Chair, Patrick McShane.
He was please to advise that the TF white paper has been approved by the StdsSC and
now posted on the IEEE TC web site section on Standards. Mr. McShane encouraged
those involved with developing or revising existing standards to review the white paper
to determine the proper use of terms and inclusions regarding insulating liquids.
Sanjay Patel put forward a message at the F15 SCIF meeting that he is concern that there
is no clear guidance on acceptable limits for DGA after overload heat runs. Customer
specified limits are “all over the place”. He believes that C57.130 might be a good place
for the addition of limits for overload heat runs. Perhaps C57.119 would also be an
acceptable place.
Representatives of Mr. Patel were not in attendance of the S15 SCIF meeting and the
request will be dropped unless they (or others) bring it up in a future meeting.
G.3 New Business
Sue McNelly spoke regarding her plans to set up a section in the IEEE TC web
site a means to access white papers such as that being produced by the TF on
particle count limits in mineral oil.
Jim Thompson spoke to thank David Sundin, Tom Prevost, and Juan Castellanos
for their contributions to the revision of C57.130.
The SCIF Chair gave a recognition to the years of contributions to the SCIF by
Don Cherry. Don announced his participation with the TC is ending at the
conclusion of the F15 meeting.
G.4 Adjournment
Approval to adjournment was made made by Don Cherry, seconded by Deanna Woods.

will need to move ahead with a placeholder for the results, while we continue to work on the data
security issues.
Data Situation
• Commercial Concerns
• IEEE & NDA
• IEEE Protocol Update
Task Forces
• Data – Norm Field, Luis Cheim, Claude Beauchemin
• Data Protocol – Don Platts, Sue McNelly, Tom Prevost, Erin Spiewak
• Diagnostic Methods – Michel Duval, Dave Wallach, Jim Dukarm
• Case Studies – Paul Boman, Arturo Nunez
• Arc Furnace TRs – Tom Lundquist
• Bibliography – Jerry Murphy, Tom Prevost
• Network TRs – Dave Hanson
• Framework – Jim Dukarm, Dave Hanson, Rick Ladroga
Claude indicated that he has been working on the interpretation portion of the data to introduce the
Duval Triangle and the Duval Pentagon, and possibly the NEI index.
A short presentation on the Duval Triangles and Pentagons by Claude will be presented later in the
meeting.
Updated Case Study information was provided by Paul Boman and an updated Bibliography section
was provided by Jerry Murphy. They have been posted for review on the website.
Diagnostic Methods (Duval Pentagon) – Presented by Claude Beauchemin
Some corrections to the information that was presented in the meeting have been made below by
Michel Duval.
Duval Triangle 1
• Introduced in 1973
• Visual method
• Uses 3 gases: CH4, C2H4 and C2H2
• Computes the relative % of each of the 3 gases
• Each type of fault is assigned a zone
• Related to Gas Formation Temperature
Duval Triangle 1: Temperature of gas formation
Annex G
Page 7 of 14
Duval defined several Zones
• PD Corona Partial Discharges (top of triangle)
• T1 Low Temperature < 300 ºC
• T2 Medium Temperature 300 - 700 ºC
• T3 High Temperature > 700 ºC
• DT Discharges and Thermal
• D1 Discharges of Low Energy
• D2 Discharges of High Energy
Duval 1 compared to IEC 60599
• Same fault designations as IEC 60599
• IEC uses 5 Hydrocarbons
• IEC uses 3 ratios of 2 gases
• IEC uses look-up table
• IEC also uses a two graph representation
Duval Triangle 1
• Widely used today
• Part of IEC 60599 (appendix B)
• Will be part of future revised C57.104
• A study by U of New South Wales (Australia) indicate a success rate of 88%
The advantages of the Duval Triangle 1 Method are that it always proposes a fault identification
(it is a “closed” system as compared to 2-gas ratios methods), with few wrong diagnosis (it is
based on a large number of inspected cases of faulty transformers in service), and it allows to
visually and rapidly follow the evolution of faults with time in a transformer.
Based on the
Duval Triangles 4 and 5
• Introduced in 2008
• For mineral oil Transformers
• With faults PD, T1, T2 (Tr4) or T2-T3 (Tr5) in Duval 1
• DO NOT use for faults D1, D2 and DT
• To obtain more information on faults PD, T1, T2 and T3
• Different gases and zones than in Triangle 1
• Use H2, CH4, C2H4 and C2H6
Sub-Types of Faults Detectable with Duval Triangles 4 and 5
• PD Corona Partial Discharge
• S Stray Gassing of Oil
• C Hot Spot with Possible Paper Carbonization
• O Overheating < 250C
• ND Not Determined (probably mixtures of faults?)
• T2 Medium Temperature 300 - 700 ºC in Oil Only
• T3 High Temperature > 700 ºC in Oil Only
Duval Triangle 4, for More Information on Low Energy Faults PD, T1, T2
Annex G
Page 8 of 14
Duval Triangle 5, for More Information on Low Energy High Temperature Faults T3, T2
Duval Pentagons 1 and 2
• Introduced in 2011, 2014
• Combine Triangles 1, 4 and 5
• Use 5 gases: H2, CH4, C2H6, C2H4 and C2H2
Duval Pentagon 1
Duval Pentagons 1 and 2
• The order of gases at the 5 summits of Pentagons 1 and 2 corresponds to the increasing
energy or temperature of the faults producing these gases (from H2 to C2H2).
Duval Pentagon 1 and 2
• Pentagon 1
• PD, D1, D2, S, T1, T2 and T3
Annex G
Page 9 of 14
• Pentagon 2
• PD, D1, D2 and S
• Sub-Types of Thermal Faults
• O, C and T3 in Oil Only (T3-H)
Duval Pentagon 2
Procedure for displaying DGA points in Duval Pentagons 1, 2
• Each summit of the pentagon corresponds to one gas (e.g., H2).
• The relative % of H2 is plotted on the axis between the pentagon center (0% H2) and the
pentagon summit for H2 (100% H2).
• The same is done for each of the other 4 gases.
• The (x, y) coordinates of the centroid of the 5 corresponding points are then calculated
using the following equations
Where:
Nomenclature of “Classic” Faults
• PD Corona Partial Discharges
• T1 Low Temperature < 300 ºC
• T2 Medium Temperature 300 - 700 ºC
• T3 High Temperature > 700 ºC
• DT Discharges and Thermal
• D1 Discharges of Low Energy
• D2 Discharges of High Energy
Nomenclature of Sub-Types of Faults
• S Stray Gassing of Oil
• C Hot Spot with Possible Paper Carbonization
• O Overheating < 250C (Oil or paper without carbonisation)
• R Catalytic reactions between water and galvanized steel or rusting (100% H2)
• T3-H High Temperature Fault in Oil Only

Claude indicated that he fully expects there to be a lot of questions when we do get a first draft out
for review and comment. He indicated that Sue will be working on the formatting and cleaning up
the document prior to it being made available for review.
Claude urged members to not wait for the meeting to review and comment on the document once it
is made available. This will allow us to respond to comments during the next meeting.
Claude did a brief review of the case studies provided by Paul Boman. A question on whether the
Key Gases will be kept as they are shown in the Case Studies. Claude indicated that he had mixed
thoughts on this. He indicated that there is some work to be done on this as the actual graphs are too
strict and simplistic to be of much use.
A meeting will be held during the Spring 2016 meeting in Atlanta.
The meeting was adjourned at 5:49 pm.

Annex G
Page 12 of 14
o A motion was made by David Sundin and seconded by Don Cherry to amend the purpose. A
friendly amendment was made by Claude Beauchemin and accepted to modify the proposed
amendment. The final amended purpose as proposed reads as follows:
“There is growing interest in and usage of natural ester dielectric coolants for distribution and power transformer applications. They are being applied in new equipment and for retrofilling existing equipment. The purpose of this guide is to assist the transformer operator in maintaining the liquid in serviceable condition. This guide recommends standard tests and evaluation procedures, methods of reconditioning and reclaiming natural ester liquid, and the analysis results at which reprocessing becomes necessary. It will also address the routines for restoring resistance to oxidation, where desired, by the addition of inhibitors.” The motion passed.
The motion passed. The Chair will submit a PAR Modification request to NESCOM refecting this and the previous motion.
o A motion was made by Rainer Frotscher and seconded by Don Cherry to revise Table 3, D1816
dielectric strength value for >69kV<230kV to 55kV for the 2mm gap to align with C57.106. The
motion passed.
o A motion was made by James Graham and seconded by Derek Baranowski to modify the text in
clause 6.5 regarding processing temperatures to read as follows:
“The degassing of natural ester liquid should be carried out at temperatures somewhat different than those required for mineral oil. The processing temperature should be obtained from the insulating liquid manufacturer. These conditions will ensure thorough degasification and dehydration of the natural ester liquid prior to introduction into the transformer.”
The motion passed.
o Finally, a motion was made by Don Cherry, seconded by Derek Baranowski to sumbit draft 1.3 of
the guide, including the latest straw poll comment resolutions and the revisions approved by the
working group today, to the Insulating Fluids Subcommittee for approval to go to ballot. The
motion passed unanimously.
o A ballot resolution group was formed, comprised of Deanna Woods, Stephanie Denzer, Susan
McNelly, Claude Beauchemin, David Hanson, John Luksich and the working group officers.
A motion to adjourn was made by Don Cherry and seconded by Stephanie Denszer. The meeting
adjourned by acclamation at 3:25 pm.
Respectively submitted, Jim Graham, Secretary Post meeting Notes by the WG Chair: There will be a meeting scheduled for the IEEE TC S16 meeting. This meeting is to review the ballot results and the BRC recommendations. The application for PAR revision is due to the change in the wording in the Title to reflect updated terminology, and the Purpose was revised to include all power transformer classes. The degassing temperature included in the current Std. Guide has been determined by field experience to be too high for some if not all natural esters.

Dave Hanson shared that no progress has been made regarding the Mixing of Fluids. He made a
motion to have the Task Force start to review. Claude Beauchemin seconded and the motion
approved unanimously.
Don Cherry updated the status of Comparison of Test Methods. ASTM is responsible for the test
selection and specs for new oil while IEEE is responsible for establishing the test value thresholds.
He shared that ASTM is a year away from developing a specification for Synthetic Ester.
John Luksich announced that no additional progress has been made on the Table and shared that he
chose values for other fluids based on Mineral Oil. This lead to a discussion of how should the Table
be structured. The Task Force will need to determine whether the Table should be structured as
either Acceptance Equipment Values or Values with Available Data. Silicone Fluid was used as an
example of not having established values for equipment at higher voltages.
No additional New Business was discussed and the meeting was adjourned at 10:46 am.

H.1 Chair’s Report
The Chair, Bruce Forsyth, welcomed everyone to the meeting.
The Chair reminded everyone that this is a volunteer organization and thanked the members for their
participation and efforts. The chair thanked activity leaders for leading effective meetings and keeping
activity documents up to date.
The chair announced that the Spring 2016 IEEE Transformers Committee Meeting will be held March 20-
24 in Atlanta, Georgia. The date and location of the Fall 2016 Meeting has not been finalized. Those
present were directed to the committee website for details as they become available.
Due to the size of the group, general introductions were not made. The chair requested that each person
state their name and affiliation when addressing the subcommittee. Consultants working on behalf of
others must identify the parties they represent.
The Chair requested member input regarding the scope of the Insulation Life Subcommittee as defined in
the current IEEE POWER & ENERGY SOCIETY TRANSFORMERS COMMITTEE ORGANIZATION
AND PROCEDURES MANUAL, section 3.19. This section was read from the manual as follows;
3.1.9 Insulation Life Subcommittee
a. Study and review methods to determine maximum safe insulation temperatures, ambient
temperatures, insulation aging characteristics, safe duration of loads in excess of nameplate
(including short circuits) and to determine methods of calculating or measuring temperatures
reached during both transient and steady state loads.
Annex H
Page 2 of 9
b. Develop and maintain related standards, recommended practices, and guides for such criteria.
c. Coordinate with other technical committees, groups, societies, and associations as required.
Sanjib Som questioned the use of the word “safe” in paragraph “a” and suggested it be replaced with
“allowable”. Luiz Cheim suggested that “safe” be replaced with “suggested”. The chair took this
information under advisement.
The Chair noted that the minutes for each Activity Group should include:
The name of the activity
The date and time of the meeting
The number of members and guests in attendance. Full attendance should be recorded in the
AMS system.
The presence or absence of a quorum
A summary of the discussion. Intricate detail is not required. A separate document can be kept
to explain the reasoning for decisions that are made.
A record of the decisions made in the meeting.
If there will be another meeting. If so, state the place and time.
The Chair requested that activity group minutes be submitted as soon as possible, but no later than
December 4, 2105. The Chair asked if any felt that this date could not be achieved and there was no
disagreement from the membership.
The Chair noted that Working Groups must have a 2/3 majority to submit the document for Sponsor
ballot. The Subcommittee must achieve a simple majority to submit a document for Sponsor ballot.
New members of the Insulation Life Subcommittee were welcomed.

Meeting Minutes
Tom Prevost, chair, introduced himself, Valery Davydov, vice chair, and Deanna Woods, secretary,
of the working group. To save time the introduction of members and guests introduction was
skipped.
A quorum of the working group members were present (40 out of 78).
The previous meeting minutes were approved with Bruce Forsyth making a motion and Luiz Cheim
seconding the motion.
Annex H
Page 4 of 9
Tom Prevost also mentioned he sent out April’s meeting notes as amended. Then a motion was
made to approve the meeting minutes. Mike Barnes made the motion to approve and Valery
Davydov seconded the motion passed.
In order to save time, the WG skipped discussion of the Scope and Purpose. The effort is 2 and a
half years into the PAR therefore the WG is close to deadline.
The chair noted that some Task Forces have made great progress and others need some more work
by Late March 2016 so that the Working Group can have a document to be put out for circulation
and comments.
There is one item that needs to be addressed and it is to form a new Task Force (TF10). The TF
will take a look at moisture equilibrium curves. Bruce Forsyth has agreed to chair the TF and he
will need some help in pursuing the completion of the work. Tom Prevost asked for TF10 members
and provided Bruce’s email for volunteers to contact.
Task Force 1 - Terminology and Definitions
Task Force Leader - Jeff Golarz [email protected]
This section will list and define the terminology for moisture related phenomena in solid, liquid and
gaseous insulating materials used in transformers and reactors.
Tom Prevost asked Jeff Golarz to come forward and discuss his task force and go over the scope.
Jeff sent out the TF latest compilation of terminology and definitions to TF leaders for comments
and received no response. Tom asked if he could send the email again for response versus
proceeding with the TF on its own.
Task Force 2 - Measurement and evaluation of moisture-in-gas insulation parameters
Task Force Leader – Tom Melle [email protected]
This section describes existing measurement, evaluation and methods of moisture and other
relevant parameters in a gaseous medium. Tom is looking for scientific people to help and
someone with field experience with dew point and moisture and finally someone with historical
research.
Tom Melle has taken over for Rich Simonelli due to Rich’s time constraints. Claude Beauchemin
volunteered to assist Tom.
Task Force 3 - Measurement and evaluation of moisture-in-liquid insulation parameters
Task Force Leader - Claude Beauchemin [email protected]
This section describes the existing measurement and evaluation methods of moisture parameters
and other relevant parameters in the liquid medium of a transformer or reactor for sequential or
continuous on-line moisture assessments.
Annex H

-Karl Fisher Methodology
-Consider effect of chemical solutions used for new aged and contaminated insulating liquids
-Consider types of insulating liquid
-Relative Saturation
-Consider measurement method
-Capacitive probe
-Derived from Karl Fisher
-Effect of aging (contamination) on water solubility
Claude reported that he has been out of touch for the last year and hoped to increase the TF efforts
in the next months.
Task Force 4 - Measurement of moisture in solid insulation
Task Force Leader - Paul Griffin [email protected] / Ron Hernandez is taking lead
Ron went over the purpose that describes the methods of measurement of moisture in solid
insulation using a balance, for un-oiled insulation and a Karl Fisher method using solvent extraction
or vapor extraction for oiled insulation. Ron stated that they have reached out to CIGRE for input
and is still looking for members.
Task Force 5 - Evaluation of moisture in solid insulation using dielectric response methods
Task Force Leader - George Frimpong [email protected]
The TF has sent out a draft to capture what is needed and introduced the 6 members and stated he is
comfortable where they are in their progress.
A discussion was introduced on the make of a document and the two ways it can be circulated. The
document will be compiled and sent out for comments.
Task Force 6 - Inferring of moisture in solid insulation from measurements conducted in
liquid or gaseous medium
Task Force Leader - Valery Davydov [email protected]
This section describes methods of inferring moisture in solid insulation from that measured in the
liquid or gaseous medium for both sequential and continuous on-line measurements.
Valery Davydov provided a detailed presentation.
Task Force 7 - Evaluation of aging and end of life of solid insulation parameters
Task Force Leader- Roger Wicks [email protected]
This section describes approaches for evaluation of parameters of end of life of solid insulation
affected by moisture. The consideration of the effects of moisture, oxygen and aging byproducts in
transformer aging tests are addressed by this task force.
Roger reported no real update since the last meeting. Roger also stated that they looked at CIGRE
reports but the main issue with that was the references were not easily accessible by members of the
task force causing road blocks.
Roger mentioned that there are eight to nine members in the TF.
Annex H

Task Force 8 - Factory/workshop application of knowledge on moisture; establishing
baselines
Task Force Leader - Poorvi Patel [email protected]
This section describes a factory/workshop approach to the establishment of a baseline for each
important moisture related parameter.
Poorvi Patel reported that they expect to have a draft put together by the next meeting. Poorvi
explained that one point that is needed pertains to relative saturation and it needs to be explored in
more depth. One of the members of the TF, Shane Smith shared some works of Dr. Roizman who
was not able to make the meeting but he went through slides that the Dr. Roizman provided. Shane
also shared that they have six transformers in the experiment so far with measurements and the
equilibrium curve is yet to be determined.
Task Force 9 - Field application of knowledge on moisture
Task Force Leader - Jim Thompson [email protected]
This section lists the risks associated with moisture
Jim has passed along a draft survey spreadsheet and has yet to have final outcome returned. Jim
reported that there are 11 members in the TF. Jim was asking for field data on transformers and
where the location sampling was taken in respect to the physical location of the transformer.
Tom Prevost asked if anyone had an objection to adjourn the meeting. Meeting adjourned.

The agenda was approved unanimously without changes.
F. Review of IEEE 1276 D1.2 All
Kurt Kaineder presented changes proposed to section 4, merits of operating at high
temperatures and section 7, description of high-temperature transformers. He indicated that
figures 1 and 2 cover a range of temperature very large and unrealistic, with winding gradients
up to 90°C, and there is a need to review. Unfortunately the based data for these charts was no
longer available and a new data is required, seeking the support of the working group to
provide this information.
A modified section to cover mobile transformers was added with ODAF cooling system and
further expansion on the topic is required.
Section 4.5 to cover the merits of other transformers need additional cases for types of
transformers and the input from the working group was requested.
In section 7, description of high-temperature transformers, additional detail of the transformers
with hybrid insulation is required, in special the section for distribution transformers that were
not included on current version of guide.
Tom Golner presented his contribution consisting of a list of considerations for the design,
components and accessories for transformers operating at elevated temperatures. He also
indicated that the suppliers of high temperature liquids could provide additional
recommendations.
Mark Perkins indicated that he needs to consider that the load losses would also increase with
higher temperatures.
Craig Stiegemeier recommended the document include volume requirements for the expansion
tank for these transformers.
It was also indicated that for distribution transformers the selection of the breakers and fuses
should be also addressed in this guide.
Dharam Vir suggested to include values of DGA in the guide. It was also suggested to include
consideration for current transformers.
Tom Golner also presented a list of major insulation, minor insulation, conductor components
and core components that need to be addressed for higher temperature operation. In addition, he
presented the different type of tests that would be required to qualify these materials for their
use in transformers operating at elevated temperatures.
Annex H
Page 8 of 9
Valery Davydov indicated that the moisture in insulation also would be required to be included,
however work is underway in PC57.162 to address this subject and current guide will make
reference to this document.
Jinesh Malde pointed that required characteristics for diamond baked paper needs to be
included in this guide.
Evan Langran suggested to include the additional mechanical stresses in conductors due to their
thermal expansion when operating at elevated temperatures.
Chairman requested working group members and guests to participate in the elaboration of the
sections required and the following new assignments were made:
Dave Sundin – Clauses 5 & 6, Evan Langran – Clause 7, Attila Gyore – Clause 6, Chuck
Stevens – Clause 6, Shane Goydich – Clause 6, Jinesh Malde – Clauses 5 & 6, Dustin Davis –
Clause 6
Chairman indicated that the working group will meet again in the Spring 2016 meeting.
G. Old Business
The Chair noted that our par expires at the end of 2016, and that we need to work quickly to
complete this first draft with all of this additional input, likely in time to discuss at our Spring
meeting so we will be in a better position to request a PAR expansion prior to the end of
September 2016.

The TF on Short Circuit Design criteria reported back to the subcommittee that it agreed that IEEE should
have some short circuit design criteria in the standards.
Paul Jarmin requested collaboration with IEC and he confirmed that Sanjay Patel is on IEC group.
Phil Hopkinson confirmed that IEC is trying to expand their scope by introducing rectangular coil. He
also opined that a unified group of IEC and IEEE would be difficult and that IEC and IEEE should have
their individual committees. Both Steve Antoz and Don Platts opined that only performance and function
should be considered and design should not be touched. Paul opined that may be design review criteria
could be set.
A motion to was put forward for the TF to give recommendations on how the short circuit criteria should
be done in IEEE standards and to possibility to collaborate with IEC was proposed by Hemchandra
Shertudke and seconded by Rogerio Verdolin. The motion was overwhelmingly passed with majority in
favor, two members opposing and one abstaining.

The Agenda and the minutes from the previous WG meeting were approved (Hemchandra Shertukde,
Krishnamutri Vijayan) with no comments or amendments.
As the first Agenda Item, the Chair presented briefly to the group the comments received from Draft 4C
of the Guide for Application of Tertiary and Stabilizing Windings, most of them being of editorial
nature. The main technical question was about Clause 2.3.2 related to what will be recommended in the
document as methods to define the thermal or continuous rating of stabilizing windings.
The Chair mentioned that several of the contributors are not currently regular members of the WG and
it was informally agreed that they will be recognized on the final version of the document. Xose Lopez-
Fernandez and Nambi Shankar volunteered to support re-drawing of some figures in present Draft,
which were borrowed from literature references, to avoid potential copyright issues. Other members
will be called to help with this task too.
As next Agenda Item, Section 2.3.2 “Recommendations for Thermal Rating of Stabilizing Windings”
was presented to the group, in form of a new text already considering all editorial changes received as
comments. At the end, Table 2.4 summarizing different forms to define the thermal or continuous rating
of a stabilizing winding was presented to the group, as basis for further discussion.
Discussion on Section 2.3.2 – Thermal ratings:
It was explained how time basis for application of using all heat stored vs. IEEE Loading Guide will
provide different thermal capacity, and how system and transformer’s zero sequence impedance
network affects SW loading. A method to size SWs, which is based on papers published between the
50’s and 70´s was discussed and decision made to include in the Guide just as historical reference.
Clarification was made (B. Poulin) that for larger kVA ratings shorter time periods for unbalanced
operation of Y-Y connected transformers would be allowed. Question on definition of capacity of SW
to clarify whether of active parts or total kVA are considered will be submitted in written (R. Amos).
Members voted in favor of keeping on Methods A & B as presently stated, with none opposed.
Other relevant recommendations include to leave out consideration of harmonics external to the
transformers (deemed possible in windfarms), as it does not belong in this document. Since this is a
Guide carefully review the use of the term “recommendation” (B.Poulin). It is important to provide
range of system impedance to determine worst case for evaluation of thermal rating, as system
impedance can change through the years, or the transformer be moved to another place in the system.
Annex J

Draft 5A is in preparation, with all editorial changes already included, and will be distributed next
month, after incorporation of changes discussed in this meeting. A timeline for further processing of the
document towards its final approval as an IEEE Std. will be distributed by the Chair among the WG.
Deadline to recirculate the Draft and provide all comments is January 2016. Motion was made to
submit draft to PCS by H. Shertukde and seconded by K. Vijayan – Results of vote: 15 in favor, 1
against and 5 abstain. Timeline to submit is latest by March 2016.
As New Business, a question about recommended voltage rating specification of stabilizing windings
was brought up (A. Portillo), discussed and considered within the scope of the Guide, K. Vijayan
agreed to submit supporting text for inclusion in the Guide.
The meeting was adjourned at 10:45 AM.

Introduction of members and guests
Mark Perkins presided over the meeting as Chair. Craig Stiegemeier was secretary.
Attendance rosters were circulated for those in attendance to record their presence
and confirm their membership or guest status.
Due to the highly anticipated “Duck Walk” and the delayed start time, the
introduction of members and guests was suspended.
Attendance
A review of the adjusted membership was conducted and 38 of the 50 WG members were in
attendance. This resulted in attendance of 76% of the membership, making this meeting “official” as
a quorum was reached. In addition, 88 guests were present and 17 of those guests requested
membership. Consult the AMS system for the full attendance roster.
Agenda approval
Dan Sauer made a motion to approve the agenda and Joe Melanson seconded the motion. All
approved the agenda. Later in the meeting, a correction was made noting that the spring meeting was
held in San Antonio.

Minutes of the Spring 2015 meeting
A review of the Spring 2015 San Antonio minutes was conducted by the chair. Dan Sauer made a
motion, and it was seconded by David Murray to approve the spring minutes as written. Minutes
were approved by the membership unanimously.
Old Business
A survey was conducted with the recommendation of changes to standard C57.12.90 section 9.3.1.
The survey was sent to the all members and guests of the WG and Performance Characteristics
Subcommittee. The survey went out October 22. As of October 31, there have been 73 returns, with
58 approvals, 8 approved with comments, and 7 disapproved. To aid in a time-effective review, the
chair consolidated the returned disapprovals and approvals with comments into the following list of 9
grouped comments:
1. The bushing CT may not meet the accuracy requirement. Discussion: Sam Mehta
commented on the accuracy, as did Dan Sauer. The burden would not be significant. Baitan
Yang noted that he does not believe one CT should be used for other requirements. The
accuracy requirements for C57.12.00. Bertrand Poulin noted that the CT accuracy must be
known and traceable. Daniel Chen (sp? from Delta Star) noted that they verify the CT is
appropriate for the measurement. Ajith Varghese noted that the test is not done at full load.
Joe Melanson clarified that the CT needs to have a test and certification to confirm the ratio is
appropriate for performing the test. Bertrand Poulin noted that the burden could be an issue,
but a dedicated CT should be used for factory acceptance tests. Phase angle error is not
significant unless the power factor exceeds 3-4%. Bertrand Poulin made motion, Joe
Melanson 2nd
that the wording “an appropriate CT” be used, removing the word bushing – in
both the text and on the drawing. This passed with no objections.
a) This CT is used for current measurement only
b) Protection or Metering CT’s normally better than 0.5%
c) Use Measurement Class if available
2. Capacitor loss (0.2 W per KVAR) is not understood – Discussion: Bertrand noted
that if you only deduct 0.2kW, it may not be enough. Once the capacitors are in a
bank, losses are influenced by contact resistance. Thang Hochanh noted that a
specific device can do the measurements. They use a company to do the verification
of the measurement, and they always match within 1%. Baitan noted that traceability
is important. Using 0.2W/kVAR should give a conservative result. Sam Mehta
suggested that the wording include something like “the measured losses include the
losses in the capacitor bank.” Mark noted that it is recommended to measure losses,
when possible. Pierre Riffon noted that loss measurement of capacitors is not an easy
measurement. A single capacitor is easy, but the loss of the assembled bank is a
challenge. He believes that leaving the wording should remain as it is for this, as well
as #3 and #4. No one objected to continuing with the as-proposed version of the
wording.
a) The capacitor loss is small (1 or 2 percent of transformer loss)
b) Capacitor loss and kVAR both vary with voltage squared
c) Capacitors with higher loss can be used if loss value is known
3. Each Capacitors loss should be measured
a) It is difficult to measure loss of capacitors with PF=0.0002
4. Most test labs use capacitors on the source side.
a) Not practical for field application
Annex J
Page 6 of 28
b) Some repair shops or small labs use this simpler method
5. This method is more complicated and will be less accurate than traditional method.
Discussion: Mark noted that this method was discussed in the working group, and
that this method is equally acceptable to meet the requirement of the standard.
Everything must be appropriately calibrated. There was not disagreement with that
statement.
a) We resolved this question in our WG.
b) This method proven to be as accurate as traditional method.
6. We need to include Figure 19 for 3 phase case. Discussion: The chair asked the
group – do we need to include a 3 phase case? A vote was conducted, and no one
raised a hand believing that Figure 19 needs to be added.
a) Three phase is just 1 phase repeated 3 times
b) Present figures 15, 16, and 17 show this.
c) Do we need a Figure 19?
7. Setting Capacitors close to Transformer in Test Lab is bad Practice. Discussion: This
is a basic safety requirement. No one in the room believed that a change was
required.
a) Capacitors can still be installed outdoors
b) Losses in the cables can be accounted for
c) Field Applications this is not a problem
8. Modern Power Analyzers are most accurate at 90° Phase angle and the Error
increases as the angle decreases. Discussion: Bertrand noted that this is true for a
bridge, but not a power analyzer. Dan Sauer noted that at 90 degree phase angle, the
loss is zero.
a) Does anyone agree with this?
9. This should be in C57.152 not in C57.12.90 if it is for field use. Discussion: The
chair suggested that this is used in some factories, and not only in the field. Dan
Sauer suggested that it should be forwarded to C57.152 in addition to C57.12.90.
a) This has been used in several factories so it should be in 12.90
After the completion of the discussion of the above 9 items, Dan Sauer motioned and Joe Melanson
seconded that that the changes to section 9.3.1 as surveyed and amended by removing references to
bushing CTs be forwarded to the working group on C57.12.90 for inclusion into the next draft of the
standard. The motion passed unanimously.
New Business – Load Tap Changer Performance Test Procedure for C57.12.90: Tauhid
Ansari, chair of the working group on PCS revisions to C57.12.00 discussed the need for
including a performance test on load tap changers as part of C57.12.90 and indicated that
this had been surveyed in his working group. The chair reviewed the types of issues that
would need to be considered, and Ramsis Girgis made a motion to include this as a new
business item for the working group, Tauhid Ansari seconded the motion and it was
unanimously voted for this motion. Mark noted that this would be covered in the Spring
2016 meeting.
Ramsis Girgis offered an informative comment that the new loss measurement would
need to be performed as part of the loss measurement guide. Ed teNyenhuis requested
this comment be included in the minutes.
Chair Added working group will be meeting at the next transformers committee meeting
in Atlanta

There were nine requests for TF membership which will be reviewed on previous meeting attendance.
After the introductions, Chairman Dr. Ramsis Girgis presided over the technical portion of the meeting.
The first item on this portion of the meeting was a review of the comment resolution to C57.12.90
balloting on clause 13:
Comment: Remove reference to 50 Hz (Clause 13.5.6.1)
Response: Some overseas suppliers to NA market have 50 Hz test facilities only.
Comment: In the example (Clause 13.6.2.2), use different values for core noise and load noise
Response: 60 & 60 dB (A) were replaced with 59 & 61 dB (A)
Comment: 0.3, 1.0, and 2.0 m are not equivalent to 1, 3, and 6 ft.
Response: Impact is minimal on reported values of the noise level. This was shown in a table
presented at the TF meeting. The differences were a small fraction of a dB.
The second item presented at the meeting was a review of the comment resolution to Table 18 of
C57.12.00.
Comment: The "Comments" section for Audible Sound Level should state that the default condition for
sound level measurements is the no – load condition at rated voltage when the purchaser's specification
does not make it clear at which condition (s) the sound levels shall be guaranteed.
Resolution: Following statements have been added: “When the purchaser's specification does not
make it clear at which condition(s) the sound level shall be guaranteed, the default condition for
sound level measurements shall be the no – load condition(s).”
Annex J

Comment: Change reference to NEMA TR1-1993 tables 0-2 and 0-3 to NEMA TR1-2013 tables 1 & 2
and clarify that the sound limits in the TR1 tables are for no – load noise levels
Response: Transformers shall meet standard audible no – load sound levels as listed in NEMA TR1-
2013, Table 1 and 2.
The TF has completed its assignment of updating both C57.12.00 and C57.12.90. The next discussion
was to determine if the TF should address the development of reference load noise levels in a
continuation of the TF. As support to future work, Dr. Girgis presented measured load noise data
provided by a number of medium and large power transformer manufacturers.
The data was summarized as follows: 5 manufacturers / 9 plants, 50 Hz: 105 transformers, 60 Hz: 98
transformers, Range of MVA ratings: 20 – 1100 MVA, and all 3 – phase, 3 – limb core form
transformers
This measured load noise levels were graphically compared to Reiplinger’s equation for both the 50 and
60 Hz transformers. Adding 10 dB to Reiplinger’s equation was proposed as an approximate top
boundary value for load noise levels. This proposed reference load noise level was then compared with
the [NEMA TR1] values and the [NEMA TR1 - 10 dB] values. The proposed reference load noise
level was seen to fall between the [NEMA] and [NEMA - 10 dB] curves. This might be proposed as a
reasonable manner to estimate the reference load noise levels. A Table was presented that had the
proposed Load noise Sound pressure levels for transformers with ratings ranging from 20 – 800 MVA.
The update on the status of the IEC Noise standards was summarized as follows:
Both the “Sound Determination” Standard and the “Sound Application” Guide have been
published as FDIS (Final Draft International Standard)
FDIS is in the last voting stage prior to publication. No further modifications other than minor
editorial corrections are allowed at this stage.
The documents are presently being translated into French (As required by IEC). Publication is
expected for March 2016.
The documents are widely comparable with the IEEE Standard
At this point, a discussion was opened to the attendees to comment and suggest possible direction in
regards to whether reference load noise levels should be added to the NEMA Table TR1 or move the
NEMA table to C57.12.90 and add the reference Load noise levels to it. A good discussion with
participation of Sanjay Patel, Steve Antosz, Joe Foldi, Vijayan Krishnamurthy, and several others. The
comments included the issues with the manner in which NEMA presented its reference levels and the
proposed reference Load noise levels. The use of BIL and MVA were pointed out as being a stumbling
block if any modification or additional column would be added to the NEMA table. The discussion
talked about the history and relevance of the decades old NEMA TR1 table to today’s designs,
materials, and knowledge gained through the years on no – load noise. It was agreed that it is more
appropriate to develop more representative NEMA levels for no load noise and add those to C57.12.90
along with the reference Load noise levels. It was also brought up by the chairman that the reference
Load noise levels and Reiplinger’s equation apply only to three phase core form transformers with a 3
limb cores. There is a need to develop reference load noise levels for other transformer types (1 –
phase, other core form types, and shell form).
The Chairman then presented information on a new CIGRE WG that is being formed at this time. The
background to the need of this WG was stated by CIGRE as being the following:
No reference / guidance on typical transformer sound levels
This often results in technically unreasonable sound level specifications
Annex J
Page 9 of 28
Unnecessary high
But more recently often also too low, which often required external sound mitigation means
(sound panels / enclosures)
The Scope of this WG was stated as:
Define transformer classes with respect to sound level
Development of sound level ranges for core, load, and cooling system noise level for each of the
transformer classes
Study information on sound level legislation in different countries and compare with technical
findings.
Summary information on sound mitigation (mounting, panels, enclosures, walls around units)
Units to be considered:
Distribution and Power transformers: 10 kVA to 1500 MVA
Distinction between 1 - Ф & 3 - Ф and 50 & 60 Hz units
The Schedule and the Deliverables of this WG are as follows:
Fall of 2015: Starting the WG
End of 2017: Interim Report
August 2019: Final Report
Bertand Poulin raised a point about the relevance of sound generation as it relates to leakage flux and
current as the basis for development of a reference table. The chairman responded that there are a large
number of design parameters that determine the level of Load noise. The intent of the reference levels,
however, is to provide a boundary for Load noise levels of transformers of different sizes / ratings.
At this point, Steve Antosz raised a motion that the TF presents the following proposal to the
Performance Characteristics Subcommittee as follows: “The TF has completed its assignment of
Revising the items in C57.12.00 and C57.12.90 related to transformer noise standards and testing. The
TF requests it be assigned the task of developing new Reference No Load Sound levels instead of the
NEMA TR1 Table and Reference Load sound levels using present data and recent work in these areas.
The TF agreed to this motion without exception. Subsequent to this meeting, the PCS Subcommittee, in
its meeting on Wednesday November 4, unanimously approved this motion. The TF will continue with
the new manadate.
The meeting was concluded with a motion for adjournment

Minutes of the Working Group Meeting
Annex J
Page 10 of 28
The meeting was held on Monday November 2, at 1.45 pm. Two of the nine members were present at
the meeting so a quorum was not achieved. There were a total of 32 people present which consisted of 2
members and 30 guests. Five guests requested membership.
The Working Group was informed that Michael Thompson the current chair of Power System
Relaying Committee K communicated that the subcommittee on Substation Protection met on
Wednesday, September 16th and set up a task force headed by Jim Niemira to review the
current draft of C57.109 and provide comments back for consideration by the working group.
They will meet for the first time in January and would likely have their input ready for us after
their May, 2016 meeting. He also informed that his term as chairman of the K subcommittee is
ending at the end of this year and Don Lukach will be the new chairman.
This was followed by a presentation on transformer short circuit by the Chair as requested by
the members and guests during the San Antonio meeting.
The remainder of the meeting was spent discussing the remaining comments that were provided from
an active group working on C37.91. The comment sought clarity on the word “balanced” in section 4
for the winding fault currents since the faults could be balanced or not. Discussions were held and it
was agreed that the term balanced may not be appropriate and could be dropped. The referred current is
the symmetrical short circuit current.
The Chair then requested for volunteers to assist in revising the guide. Javier Arteaga, Kiran Vedante,
Steve Schappell, Hemchandra and Alvaro agreed to provide assistance in revising the guide. The
meeting adjourned at 2.40pm.

Memphis, Tennessee, USA
Monday, November 2, 2015
3:15 PM – 4:30 PM
Chair: Richard Marek Secretary: Samuel L. Sharpless
The third meeting of this working group took place at the Grand Ballroom of the Peabody Hotel. The
meeting was called to order at 3:20 PM by Richard Marek, Chairman.
13 members were present at the start of the meeting, representing a quorum of the 26 registered
members. One member arrived late, representing a total attendance of 14 members. There were 35
guests and 2 of those persons requested membership.
Annex J

The minutes of the April 13 2015 meeting in San Antonio, Texas were presented for approval. A
motion to approve the minutes as presented was made by Tim Holdway and seconded by Robert
Ballard. The motion passed unanimously.
The meeting agenda was presented for approval. A motion to approve the agenda as presented was
made by Phil Hopkinson and seconded by Sheldon Kennedy. The motion passed unanimously.
The chair stated that all changes proposed to date were reflected in draft #3 which had been previously
mailed to all members and guests.
The chair discussed annex C, which includes excerpts from “Corrected Winding Eddy-Current
Harmonic Loss Factor for Transformers Subject to Nonsinusoidal Load Currents” by Elmoudi,
Lehtonen, and Nordman. He stated that the information in this particular paper is the best of 40 or 50
documents reviewed and it addresses some long standing criticisms of the C57.110 document for not
including skin effect in the calculations. There were no comments by the membership on this issue.
Section 6.2, which shows how to calculate transformer parameters using certified test data and provides
calculations for other loss parameters, was discussed. There were many comments about the
recommended assumption that 33% of the total stray loss for liquid immersed transformers is due to
winding eddy losses. Hasse Nordman suggested the number be changed to 50%, while Sheldon
Kennedy was content with the 33%. The chair commented that 33% could be good for wire windings
and 50% for foil windings, although the typical user would not know the winding construction. Dhiru
Patel reported testing which indicates that smaller transformers have much smaller losses and
recommended testing the transformer at multiple frequencies. The chair noted that the intent is to
provide guidance for transformers that are already energized so this type of testing in the field was not
possible. Hasse Nordman stated that he has reviewed data on many transformers from 31.5 MVA to
230 MVA which suggests that the percentage should be about 40% for inside windings and 60% for
outside windings. Tank shunts will often increase the outside winding percentage to 80%. Low voltage
windings are often in parallel which can make calculations difficult. Phil Hopkinson observed that
there are many variables and suggested a 50 percent figure in order to be conservative. Sheldon
Kennedy stated that the percentages for distribution transformers are lower than for bigger transformers
or specialty units. He suggested different sets of numbers for different transformer sizes. Others noted
that C57.18.10 suggests 60%. Joseph Foldi expressed concern that it may not be possible to use one
number for all transformers, so users should consult transformer data reports whenever possible.
Aniruddha Narawane noted that most data reports do not state eddy losses. Javier Arteaga raised the
issue of differences between liquid and air cooled units. He also discussed differences between the high
voltage and low voltage windings. He expressed concern that using 50% would be too generic. Alvaro
Portillo noted that this percentage is very much relative to the design of the transformer and it would be
risky to assume one number for all cases. Sanjib Som supported using 50% with qualifiers about the
assumptions involved.
The chair noted that the method in section 6.2 is much more likely to be used for pad mount distribution
transformers, 500 KVA and below. There was general agreement that a 50% figure is acceptable for
typical pad mounted distribution transformers, so the chair agreed to edit section 6.2 such that it
recommends 50% with the appropriate qualifiers and then circulate the wording for all to review as an
official survey.
Dhiru Patel stated that he would provide data from CSA 802.5 that would be useful in qualifying the
section 6.2 values. Alvaro Portillo stated that he has a large number of transformer measurements in a
database that can be analyzed by KVA range as well. The chair heartily encouraged Patel and Portillo
to provide their data for circulation.
Annex J

Tom Holifield questioned if equation 21 should have I per unit squared added, observing that it is
simply equation 16 divided by equation 2. The chair agreed to review the issue and compare it to
previous editions.
There were no other comments offered. The chair encouraged all to read and comment on the
document before the next meeting.
Sanjib Som made a motion to adjourn the meeting, it was seconded by Phil Hopkinson, and passed
unanimously. The meeting was adjourned at 4:30PM.

UNAPPROVED MINUTES
The PCS Working Group on General Requirements for C57.12.00 met on Monday, November 2, 2015.
The Chair Tauhid Ansari called the Group to order at 16:45 and explained purpose and scope of the
WG. 49 Members and 78 guests were present, and as Working Group membership stands at 72
members, we did have a quorum and were able to conduct official business. The following 11 guests
requested membership:
Amitabh Sarkar CG Power Systems
Hugo Flores CG Power Systems
Kevin Sullivan Duke Energy
Kirk Robins Exelon Generation
Oscar Pinon Voltran WEG
Reto Fausch RF Solutions
Rodrigo Ronchi WEG
Shirish Mehta Mehta Consultants
Tim-Felix Mai Siemens AG
Verena Pellon Florida Power and Light
Waldemar Ziomek CG Power Systems
The Agenda and the minutes from the San Antonio meeting were approved (Sanjib Som/ John John,
and Kenneth Skinger/Philip Hopkinson, respectively), with no comments or amendments.
Next, the Chair presented the first Agenda Item to the WG.
A. OLD BUSINESS
1. WG Item 97, Table 18 Operational Tests of LTC Equipment
A motion was passed in previous WG meeting for sending the survey to members and
corresponding member to approve adding the LTC operation test in C57.12.00 Table 18, so that
Annex J
Page 13 of 28
WG C57.12.90 could work on the details of test procedure and acceptance criteria. The test
should be a routine test and be applicable to Class I and Class II power transformers.
The proposal was approved by 91% of the Members who responded, 7% disapproved and 2%
abstained. The main technical comments received were presented to the Group and resolved. A
motion was made by Sangib Som/Rogerio Verdolin, to leave out the part of “Comments”
originally in the proposal to modify Table 18; the motion passed with no members opposed.
2. WG Item 102, Sec 5.12.1 Remove "Metal" from first paragraph
This item is related to first paragraph of Section 5.12.1, where it is requested that the transformer
nameplate specifically be made of metal. The subject was discussed during the meeting, with
main argument against that the nameplate should be readable after a period as long as 30 years,
questioning if softer, synthetic materials would endure.
A motion was made by Don Ayers/Phil Hopkinson to keep the request for metal on Section
5.12.1. The motion passed with no members opposed.
3. WG Item 103, Sec 5.5.2 - Remove “and shall be based on the turn ratio”
Section 5.5.2 “Voltage ratings” of C57.12.00 requests that “The voltage ratings shall be at no load
and shall be based on the turn ratio”. The proposed change was discussed with argument in favor
that voltages on nameplate should be mainly based at the no load voltage.
A motion was made by Mark Perkins/Dharam Vir to remove the part of voltage ratings being
based on turns ratio. The motion passed with 21 members in favor and 3 members opposed.
4. WG Item 104, Sec 6.1 – Discuss the P dimension that affects the
interchangeability of bushings
Section 6.1 of C57.12.00 reads as: Bushings that have dimensions in accordance with IEEE Std
C57.19.01 [B25] shall have bushing mounting holes that are adequate to accommodate the
maximum “P” dimensions for those bushings, as shown in the applicable tables.
The WG Chair clarified that the manufacturer of the transformer design the CT’s close to bushing
size, so bushings can only be changed for others identical in design. Ed TeNyenhuis suggested to
pass the question to the Bushing Subcommite and Steve Snyder recommended to first ask Keith
Ellis about the fundamentals for that comment, and try to resolve the question within WG
C57.12.00.
The subject was tabled for the next WG meeting.
B. NEW BUSINESS
Given the time, no New Business was discussed and the meeting was adjourned at 18:00 hrs (Eduardo
Garcia/Aniruddha Narawane).

Tuesday November 3, 2015 – 9:30 to 10:45 AM
The meeting was called to order at 9:30 AM by Chairman Sanjib Som
There were a total of 72 participants: 11 Members and 62 Guests out of which 7 Guests requested
membership.
The meeting was opened with the introduction of participants and the circulation of attendance
roasters.
11 of the current 22 WG Members were present and quorum to carry out business was met.
Meeting notes:
Meeting Agenda
Meeting agenda, which was circulated among members and guests on October 12th, 2015 by
email, was presented to the audience.
Motion to approve the agenda was made by Luc Dorpmanns and seconded by Enrique
Betancourt.
There were no objections or comments and the F15 agenda was approved.
Minutes from previous meeting
The minutes from the S15 meeting in San Antonio, which were circulated on September 30,
2015 by email, were presented to the audience.
Motion to approve the meeting minutes was made by Luc Dorpmanns and seconded by Klaus
Pointner.
There were no objections or comments and the S15 meeting minutes were approved.
Old Business:
1. Bertrand Poulin: Draft proposal on definition of Linearity and Loss
measurements/evaluation:
Bertrand Poulin presented a write up with a draft concept on proposed changes or additions to the
standard on topics regarding the measurement and evaluation of impedance linearity as the
present standard lacks specific methods. Also, Bertrand introduced a proposal on using a DC
method and Ldi/dt and discharge current approach to quantify linearity whenever AC methods are
not feasible. An example based on a single phase reactor was presented.
Issues with magnetic hysteresis affecting the DC measurement were discussed at request from
Joseph Foldi.
Enrique Betancourt mentioned that additional data or a paper to demonstrate correlation between
the AC and the proposed DC method would be needed.
The write up also proposes a more specific way of measuring and evaluating the losses based on
power factor kW/KVAr or kW/KVA.
Annex J
Page 15 of 28
This draft document will be circulated by the WG Chair among the members and guests after the
meeting as material for discussion.
2. Luc Dorpmanns: Presentation of draft proposal to add variable shunt reactors (tap changer
type) in the standard.
Luc Dorpmanns presented a write up on the topic of variable shunt reactors. As informative
point, it was mentioned that this topic is also covered in a next to be published document under
CIGRE WG A2-48.
This write up also includes vibration limit recommendation 200 µm/pp and noise measurement at
full voltage.
This document will be circulated by the WG Chair among the members and guests after the
meeting as material for discussion.
Other topics discussed:
Luc Dorpmanns brought up the issue as to why the linearity is specified by end users to 1.2 or
1.5 nominal voltages. Is this reasonable? Over-specifying?
Bertrand Poulin indicated that the request is based on system studies as load shed on long
transmission lines result in over voltages of such magnitude lasting for several seconds and
the shunt reactor must be able to perform its function when energized at as such voltage
levels. Additional input from end users is needed to clarify this topic as manufactures don’t
have enough information on this.
Jane Verner made a suggestion that for variable shunt reactors, nameplates should be
provided with a table of MVAR at each tap position. Jane will clarify her request to the WG
Chair in a form of a write up to be discussed in the next meeting.
Dieter Dohnal offered to provide a write up on on-load tap changers for variable shunt reactor
application. Dieter to send the information to the WG Chair for discussion in the next
meeting.
The WG Chair indicated that the standard will be saved on the updated template so each of
the subgroups could start formatting the document by next meeting.
Subgroups as agreed during S15 meeting are to work on different sections of the
standard. The following members volunteered to work on:
Sections 1 through 4: Sanjib Som, A. Del Rio.
Sections 5 through 9: David Joe Meisner, Subash Tully, Rogerio Verdorin, Raj Ahuja.
Section 10: Bertrand Poulin, Shamum Hakim, Subash Tully, Klaus Pointner, Kris
Ploetner
Sections 11 and 12: Mike Sharp

Hemchandra Shertukde made a motion to accept the minutes from the Spring 2015 meeting and was
seconded by Dev Walia. The motion passed unanimously.
The secretary gave a summary of the status of the standard. The standard has been through one ballot
and received 132 comments. The IEEE comments have been addressed and resolutions recommended
to the comments received from IEEE members. The IEC comments have been received but not
resolution meeting has been held. The meeting is scheduled to occur in January 3-26 with Casey
Ballard, head of the Resolution Committee, will also attend.
After further discussion and a recommendation from Jodi Haasz, it was concluded that a two year PAR
extension should be requested immediately.
Annex J

Alvaro Portillo, Consultant from Montevideo, Uruguay made a presentation of failures occurring on
wind turbine transformers located in the nacelle of a wind turbine located near the ocean. Primary
failure mode was a creepage failure due to accumulated salt in nacelles open to the outside atmosphere.
Similar units with nacelle sealed to the atmosphere did not see the same failure modes.
He also noted that fluid filled transformers were exhibiting leakages early in their life. Cause was
determined to be metal fatigue due to repeated pressure cycling caused by repeated dailyload cycling. It
was recommended that a test be included in the standard to perform a 10,000 cycle pressure test to
determine ability of transformer tank to withstand mechanical cycling due to loading.
Martin Navarro said the he has a new IEEE technical paper just recently published that also addresses
the issues raised by Mr. Portillo. Further discussion was held on the presentation by Evan Langran,
David Walker and Dev Walia.
It was proposed that the proposed test be included in the standard. It was decided that with the standard
in the comment resolution cycle, it may not be possible to add the mechanical test to the standard before
approval. The secretary was to research the possibility for inclusion and report back at next meeting.
Joe Mango gave a verbal discussion of recent discoveries of leaks found on 650 wind turbine
transformers. His conclusion was similar to Mr. Portillo’s relative to mechanical cycling. Also being
examined as to whether units with high hydrogen content have higher leak rates.
Phil Hopkinson asked the question to the group as to whether additional gas space would minimize the
mechanical cycling and asked others to think about it. The Chairman will be asked to send out a survey
to ask this question and whether other solutions may exist.
Tim Holdway moved and Paul Jarman seconded a motion to adjourn the meeting. The meeting was
adjourned at 10:15 CST.
A working group session is planned for the Atlanta meeting.

2. The meeting was called to order at 11:00 am on Tuesday, November 3, 2015.
3. The chair indicated 16 members at the time and 13 were present during roll call therefore
establishing a quorum.
4. A motion was made by Stephen Shull to approve the minutes of meeting from the Working
Group Spring 2015 meeting in San Antonio, TX. The motion was seconded by Said Hachich.
By unanimous vote, the minutes were approved.
5. The chair went some history and comments from previous meetings to update everyone on
current status as the previous chair could not continue after Spring 2015.
6. A request was made for the DOE report discussed in last meeting. Jerry Murphy will try and
contact Don Duckett and obtain a copy.
7. Discussion took place on the subject of using dollar values in this document. Previous
comments by Don Platts and William Bartley indicated that IEEE legal would not allow
dollars to be used. Erin Spiewak (IEEE-SA) read the IEEE response. Dollars can be used
provided they are publically available numbers (preferably from government-sponsored
sources). If public data are not available, then use arbitrary numbers that bear no relation to
reality and that do not reflect actual relative costs or prices. The 1991 published version is an
acceptable format. The use of a generic symbol is not preferred.
8. The chair requested help from the Working Group to review the existing list of items in the
document. Two volunteers (Ewald Schweiger and Ryan MacMullin) were found.
9. The chair continued reviewing the latest draft and mentioned that members need to review all
calculations.
10. Phil Hopkinson asked if anyone had a “magic number” for the cost of transmission and
distribution as $/Watt. Said Hachichi offered some factors. Phil then asked for an industry
average because those appear to be too high. Another offered a typical that Phil agreed were
more to his thinking. [It is not in keeping with the Transformers Committee policy to offer
industry financial factors.]
11. As an item of new business, Dan Blaydon asked about the previous meeting comment “Due
to timeline, utilities that do not generation anymore, deregulated utilities would not be
included in the document.” His concern is that this document doesn’t address non-vertically
integrated utilities (no generation) and how to incorporate this document.
12. Don Platts suggested that a group be formed to determine what is needed in the document
that will help the utilities as it really belongs to the users.
13. The chair asked if Dan Blaydon would lead getting a group together for this task and other
volunteers were requested. The following is a list of these volunteers:

a. Members: 10
b. Guests: 18
c. Guests requested membership1 (Samuel Sharpless)
d. Total: 28
2. The meeting was called to order at 1:45 pm on Tuesday, April 14, 2015.
3. Chair presented agenda for the meeting. A motion to approve agenda for the meeting was
made by Charles Simmons and was seconded by Said Hachichi.
4. A motion was made by John John to approve the minutes of meeting from the Working
Group Spring 2015 meeting in San Antonio, TX. The motion was seconded by Alejandro
Macias. By unanimous vote, the minutes were approved.
5. Par status: Par expires December 31st, 2019, which represents 7 meetings before we have to
conclude the guide before going to ballot.
6. Rogerio Verdolin and David Walker provided a review of their findings related to the
references included in the current revision of C57.105. Of the 34 references listed, 9 are
general reference textbooks and similar publications, 2 are papers on converting from two to
three phase power and vice versa, and 23 are references on ferroresonance. None of these
materials are directly referenced in the body of the standard but are included solely to provide
additional information for the reader. In general, the cited works are from the 1950’s, ‘60’s,
and early ‘70s. Many of them are out of print and difficult or impossible to obtain. In
addition, since discussion of ferroresonance is just a small portion of the standard, having 2/3
of the references being information on that topic seems out of balance with the content of the
standard. Given these considerations, it was decided to update the references to fewer, more
modern, references that would be easy for interested readers to obtain. Examples are the
Annex J
Page 20 of 28
CIGRE guide on ferroresonance and also more modern summary publications on the topic.
We have contacted David Jacobson, from Manitoba Hydro, an expert on ferroresonance and
one of the authors of the CIGRE guide, and he has agreed to help us find appropriate,
modern, references on ferroresonance. We are also going to look for more modern, easy to
obtain, general information on transformer connections to supplement or perhaps replace
some the out-of-print textbooks listed in the current references.
7. John John has reviewed the comments from the excel file presented by the chair which was
the previous Reaffirmation balloting comments. John has reviewed the comments attached in
excel file, one by one. They are valid in most cases as far as the disposition detail is
concerned. A few seem to be already done. Others are yet to be incorporated. We can include
those as going forward. However, the comments that all references to reference standard
need to have the year updated doesn’t seem necessary. While working in another group, what
we decided is there is no need to mention the year or revision year of the reference standard
when we refer an ANSI standard as they are continuously revised and no point in mentioning
the year. If we refer a document or paper, then original date of the document or paper is still
ok, irrespective of how old it is. If in the present context, they are not valid, we can remove
reference to those documents. John has marked up what he found out and noted down briefly
what need to be done on the hard copy of the file print out, as discussed with Adam Bromley.
John has handed over the marked up review to Adam for making the draft modification of the
Guide before the next meeting.
8. Adam presented and discussed the keywords from the Abstract section for searching purpose.
The word “connections” was included.
9. Adam also presented the additions he made to the Introduction for informational purposes.
There was general consensus surrounding the additions.
10. Samuel Sharpless will produce the document drawings in AutoCAD or similar drawing
format so that they can be easily edited during the revision.
11. Charles Simmons asked if the draft document would be posted to the Transformer Committee
Web site. Chair stated that once we have a document that includes the figures, tables and
equations in a viewable format, we would be able to post the draft. The chair’s hope is that
this is completed prior to the next meeting in the spring.
12. The next meeting is March 20-24, 2016 in Atlanta, GA.
13. The meeting adjourned at 2:35 PM

rejected, but only 13 of these 23 were related to the Disapprove vote and the request for the comments
to be resolved (9 out of these 13 are from the same commentator and were rejected based on the fact
that the comments have a very generic character and no specific proposals have been provided).
Annex J
Page 22 of 28
3. The marked Guide Draft 6.1 that incorporates all accepted changes was reviewed.
Several specific aspects were discussed:
a) Single phase inverters (also known as micro-inverters) – multiple inverters of this type
can be connected to one transformer LV winding.
- P. Hopkinson moved the proposal to include the note on the importance of the
consideration of synchronization of these inverters.
- V. Tendulkar commented that modern inverters are tightly controlled and this is not
normally a problem.
- T Hollis also thought this is not an issue.
- P. Hopkinson made a motion to include the note on the discussed topic in the revision of
the Guide. A. Portillo seconded. Motion passed, with 1 against and 1 abstain. P.
Hopkinson will provide a wording of the comment.
b) Winding connection examples (Fig. 7)
- A. Portillo commented on the Fig. 7 c) (left case) that this is not a feasible Winding
arrangement. He made a motion to delete the case. A. Narawane seconded.
- In the discussion, V. Tendulcar was concerned about cases d) and e) as well. It was also
proposed to eliminate 7c) left, d) and e) cases.
- E. Betancourt proposed to indicate the central HV lead for cases 7c) left. A. Portillo
accepted the friendly amendment to his motion and the motion to include the central lead
for the case 7c) has passed unanimously.
c) Harmonic content.
- P. Hopkinson made a motion to include the harmonic level vs. frequency Table from
IEEE 518 in the Guide to ease the users access to the data. He described the case where
lower level high frequency (3 kHz) harmonic has been generated due to the resonance
and was detrimental to the transformer. A. Portillo seconded the motion.
- T. Hollis thought that IEEE 1547 is a more appropriate reference.
- 8 members voted for, 2 against and the rest abstained. Motion passed and the Table will
be added.
4. The next revision of the Guide (Draft 6.1) was discussed.
Ballot Comments Resolution Committee has had a conference call on October 29, 2015 and
recommended to submit Guide Draft 6.1 for the ballot re-circulation.
S. Som made the motion to approve Guide Draft 6.1 (with the changes approved at this WG meeting)
and submit Comment Resolution and Draft 6.1 for the ballot re-circulation. S. Walia seconded. The
motion has passed unanimously. Draft 6.1 will be submitted for the re-circulation.
As a new business, H. Shertukde mentioned that the WG will present a tutorial on DPV generation and
transformers at the next IEEE TC Spring meeting 2016 in Atlanta. This WG is scheduled to make a
tutorial presentation at the next Spring meeting in Atlanta Georgia. Tom Prevost has been intimated to
include the topic for the tutorial. Speakers to be included in the team to present the tutorial have been
initially contacted.

TF on HV & EHV Transients C57.142 - J. McBride J.8.12
TF to Investigate the Interaction between Substation Transients
and Transformers in HV and EHV Applications
Memphis, TN
Tuesday, November 03, 2015
3:15 PM – 4:30 PM
Ballroom C
Chairman – Jim McBride
Secretary – Tom Melle
1) Welcome and Chair’s Remarks. TF objectives were presented.
2) Circulation of Attendance Sheets
3) There were 88 individuals in attendance with 21 members present. Quorum was
achieved.
4) Spring 2015 Meeting Minutes presented and approved with no opposition
5) Fall 2015 Agenda presented and approved with no opposition
6) Chair began presentation and discussion of Capacitor Switching Transients
There was a review of comments submitted by Pierre Riffon on the methods of
describing capacitor bank switching operations. The three methods were simple
LC circuit, back-back capacitor banks switching, and traveling waves. The Chair
remarked that after reviewing the failures in this category, none had been
identified as the primary cause of the failure. The Chair presented a few example
traces that supported this conclusion.
Phil Hopkinson commented that a data capture of recorded waves should be
presented if conclusions are made; however agreed that Capacitor Switching
typically does not cause failures.
Chair briefly reviewed the case studies which are a basis of the TF work and described
the failure categories that have been identified in the preliminary task force paper:
A - System faults and capacitor switching produces traveling waves with
reflections that excite lightly loaded transformers to resonance.
B – Generator step-up transformers operating in back feed mode are excited to
resonance by system transients.
C- High frequency switching operations close to the transformer terminals which
excite internal resonance due to multiple re-ignitions and re-strikes.
Chair requested that the members of the TF make a motion on the inclusion of capacitor
bank interactions in the TF summary paper. Pierre Riffon restated with capacitors there
Annex J
Page 24 of 28
is no fast collapse to ground. Phil Hopkinson made a motion that capacitor banks be
included with indication of factors that may or may not contribute to failure. The motion
was seconded by Rogerio Verdolin. Motion passed with 19 approvals.
7) The Chair indicated that new switching transient information on re-strikes during bus de-
energization transients had been received from Pierre Riffon (~ 300-500 kHz). This new
information was added to Failure Category C: High frequency switching operations close
to the transformer terminals excite internal resonance due to multiple re-ignitions and
restrikes. In addition, Figure 2 was added to the document.
8) General discussion, suggestions and comments regarding the Conclusions /
Recommendations section ensued:
Xose Lopez suggested adding monitoring and mitigation information to the TF
paper. This suggestion was discussed by the members of the task force and those
present expressed no objections to adding this information. During the discussion
of monitoring, modeling, and system studies, Bertrand Poulin suggested that all
these tools must be utilized to realize a complete understanding of system
interactions.
Sanjib Som suggested separating the Conclusions and Recommendations sections
and also suggested that the TF summary paper be submitted for publication as an
IEEE transaction paper
Rogerio Verdolin mentioned that proper instrumentation is required to measure
these high frequency transients in the field. The Chair suggested that these
measurement devices should have a bandwidth of at least 2 MHz.
Waldemar Ziomek indicated that he was involved with transient studies that
indicated the stress on a transformer can vary significantly due to the methods of
neutral grounding used on the unit. Alvaro Portillo agreed with this statement.
Discussion ensued over resonant frequency and the severity to neutral grounding
and its effect on the response of the transformer. There was discussion that this
may not be material for inclusion in the TF summary paper. Waldemar Ziomek
made a motion to include this information as possible material for revision of
C57.142. The motion was seconded by Pierre Riffon and passed.
The Chair commented that design reviews be expanded to include these neutral
grounding topics, stressing the need for good communication between transformer
manufacturers and end-users.
9) An update from the CIGRE Modeling working group presented by Xose Lopez will be
made available to the task force.
10) Phil Hopkinson presented possible upstream/downstream interactions of two
transformers. Low power factor / highly inductive combinations were emphasized.
Again, this presentation will be made available to the task force and might be considered
for inclusion in the C57.142 revisions.
11) Chair indicated that some more specific information had been added to the GSU back
feed section of the TF Paper. This information was provided by Bertrand Poulin.
12) New Business – none presented
13) A motion to adjourn the meeting was made by Joe Melanson and seconded by Xose
Lopez. The meeting was adjourned at 4:30PM.

WG on Semi-Conductor Rectifier Transformers -C57.18.10 - S. Kennedy J.8.14
Task Force for Semi-Conductor Rectifier Transformers
Meeting Minutes – November 3, 2015
Memphis, Tennessee
Sheldon P. Kennedy - Chair
The Task Force met on Tuesday, November 3, 2015 at 11:00 AM with 6 members present. Sheldon
Kennedy chaired the meeting. This was the first new meeting for a Task Force since the spring of 2011
in San Diego.
The Task Force was formed to develop a new PAR for a revision that is due for the standard.
There was a lively discussion about problems with newer adjustable speed drive transformers with
PWM or AFE drives. Many of these produce uncharacteristic outputs. Other, issues that had previously
been discussed, like electrostatic ground shields and phase shifted windings were discussed again.
The meeting turned back to developing a new PAR. A change in title was discussed but rejected. The
concern was that the title can make a user of the standard believe it only applies to rectifier transformers
and not to inverter transformers or adjustable speed drive transformers. These will be added the Scope
of the PAR.
It was requested to lower the Scope of the PAR to “200 kW and above” from “300 kW and above” for
single phase loads Also, three phase loads were lowered from “500 kW and above” to “300 kW and
above”.
Also, Dhiru Patel requested that we add to the excluded list “If a user connects mixed loads with more
than 10% non-converter fundamental frequency power content, IEEE C57.110 shall apply”. The Chair
will check with the Performance Characteristics Subcommittee on whether this is appropriate for the
Scope or whether it should be in the body of the document before submitting the PAR to Adcom.
All other portions of the previous C57.18.10 Scope will be kept.
There was discussion about whether a joint document with IEC 61378-1 Converter Transformers – Part
1, would be of interest. The Task Force felt this was premature and that while there are many common
treatments in both documents, there are also significant differences at this time. A revision of IEEE
C57.18.10 must be accomplished by December of 2019, so there is little time for this. The Chair will
ask IEEE to procure a copy of IEC 61378-1 for harmonization work on the new C57.18.10 revision.
While this work is being accomplished, notes will be made of common and different treatments for
possible harmonization of the two documents into one in the future.
The Chair again made a call for additional Working Group officers. William Whitehead of Fuji Electric
volunteered to be Vice Chair to help with the work. The Chair would still like to also add a Secretary to
the future Working Group.
The Chair will complete the PAR form for review by the Task Force and then submit it to the
Performance Characteristics Subcommittee to be approved by Adcom.
There were no further comments.

TF Short Circuit Criteria - D. Buckmaster J.8.15
Task Force Short Circuit Criteria
Memphis TN, USA – Nov 3, 2015
Ed teNyenhuis, Nov 3, 2015, Rev 1
The Task Force met at 4.45 PM in the Grand Ballroom A on Nov 3, 2015
This was the first meeting of the task force
The scope of the task force as given by the subcommittee was to: Investigate to have a short
circuit design criteria similar to the IEC Annex A, Theoretical evaluation of the ability to
withstand the dynamic effects of short circuit, in the IEC 60076-5, Ability to withstand short
circuit.
Dave Buckmaster was not able to attend as Chairman so Ed teNyenhuis acted as Chairman for the
meeting
An attendance roster was circulated with 42 requesting membership and with 36 guests. Since
this was the first meeting, all persons requesting membership were immediately granted
membership by the Chairman. Thus quorum was achieved for the meeting.
Joe Foldi first gave the background of his request (he initiated the request at the Spring 2015 PCS
meeting):
Most manufacturers can calculate fault current and forces/stresses however the mechanical
material characteristics are only known from testing
GE Pittsfield has done a lot of short circuit and material testing many years ago and this is the
basis for the Annex A
TC14 has realized that the Annex A needs to be updated and has set up a WG that will start in
January 2016
Question is if IEEE needs to do something similar to Annex A?
If yes then how would IEEE handle this? Should we do our own guide, do a dual guide with
IEC etc?
There was excellent discussion on this subject from manufacturers and users:
IEC is looking itself at doing a dual document (Phil Hopkinson)
IEC document is only presently for oil filled circular core power transformers (Alvaro
Portiillo)
Short circuit testing has an overall 25% failure rate and 40% failure rate for > 100 MVA
(Alvaro Portillo)
IEEE should have better motivation to do something than just the IEC Annex (Waldimar
Ziomek)
IEEE does not tell manufacturers how to design transformers (the IEC Annex A does)
(Waldimar Ziomek)
IEEE should take part in the IEC but should not change IEEE guides (Waldimar Ziomek)
A new IEEE guide on SC would still allow manufacturers to follow their own rules (Joe
Foldi)
The IEC Annex A shows a disconnect in the interpretation of the reality of short circuit (they
need to be revised) (Sanjay Patel)
Annex J
Page 28 of 28
The IEC Annex A is not solely based on GE information, but also or more so on CIGRE
Brochure-209 (Sanjay Patel)
IEEE should participate in the IEC to correct the Annex A (Sanjay Patel)
IEEE needs something to give users a good feeling that manufacturers know what they are
doing for SC (Kushel Singh)
Even though 40% of > 100 MVA transformers failed they all had thorough design reviews
(Krzystof Kulasek)
The quality and tolerances of manufacturing are very important and this should be part of the
IEEE guide if done (Krzystof Kulasek)
Would this inhibit a manufacturer from investing in new technology? (Steve Schroeder)
This should be a guide, not a standard (Bill Boettger)
It should not be design specific but should allow freedom to manufacturers (Phil Hopkinson)
Annex A is informative so it is not a standard (is optional) (Alvaro Portillo)
Manufacturers should be allowed to do their own simulation to prove the SC worthiness
(Arup Chakraborty)
SC testing is not practical for all transformers so the Annex A is a practical approach (Joe
Foldi)
Even though Annex A is optional, users will take this as gospel truth (Sanjay Patel)
Manufacturers should have something to comply to (Xose Fernandez)
IEEE needs to start with something (Amit Sorkay)
A motion “for IEEE to have a short circuit design criteria similar to the IEC Annex A, Theoretical
evaluation of the ability to withstand the dynamic effects of short circuit, in the IEC 60076-5,
Ability to withstand short circuit” was initiated by Joe Foldi and seconded by Bill Boettger. This
motion passed by 28 to 2 votes.
The meeting was adjourned at 5.55 pm.

Clause 4 Task Force Chair, Brian Penny reported that the changes to this clause primarily involved
editorial changes with some changes to references due to changes to such references, and briefly
discussed the comments that had been received. Javier Arteaga suggested that the table of ratings might
need to include reference other alternate fluids such as ester fluids, with the TF Chair stating that the TF
would review the suggestion. The TF Chair stated that clause 4 would be updated based on the comments
received.
Clause 5 Task Force Chair, Joe Watson presented for discussion several of the comments that had been
received. One commenter objected to the DETC being listed as an optional feature in Table 4, though
this was not a change from the previously approved standard. Sheldon Kennedy, who noted that he had
been a member of the WG for the previous revision of this standard, remembered that it was intentional
during the previous revision of this standard for the DETC to be optional but could not recall the rationale
discussed at the time. Several attendees shared their opinion that they preferred the DETC remain an
optional feature, while Steve Schroeder shared his believe based on his routine review of user
specifications that there is an expectation among many users that non-LTC transformers include a DETC
without their having to explicitly specify.
Annex K
Page 6 of 15
Motion was made by Wally Binder and seconded by Craig Stiegmeier for a DETC, with taps at ±[email protected]%
steps, to be a standard requirement for non-LTC transformers and to be an optional requirement for LTC
transformers. The motion passed with a vote of 11 in favor, 5 against, and 2 abstaining.
Discussion regarding this motion included comment by Jane Verner that the DETC can be an expensive
feature and they her company had eliminated it from their specification, comment from Kumar Mani that
power plants often have to change their GSU tap positions for various reasons, and comment from Eric
Schleismann and one other attendee that they frequently adjust DETC positions to ensure that the LTC or
that voltage regulators routinely run through neutral position.
It was noted that the list of Table 4 notes are intended to be normative and needed to be reviewed to
confirm adherence with the IEEE Style Manual convention for table footnotes.
A suggestion was made by Paul Jarman to update the term LTC to OLTC. The clause 5 TF Chair said
that the TF would consider this. It was additionally pointed out that this might require the inclusion of
OLTC in the definitions of the document.
Sue McNelly stated concern that there is no standard for the location or numbering of tertiary bushings.
The clause 5 TF Chair said that the TF would review. Sue McNelly also volunteered to join the clause 5
Task Force.
Clause 6 Task Force Chair, Mark Tostrud reviewed proposed changes to this clause.
One proposed change was for the removal of the drain valve sampling valve as a requirement. It was
pointed out by Don Platts that an associated ASTM states to use that particular sampling valve and that
removing it as a required feature in the standard would need coordination with that group.
It was noted that sections of the clause concerning control equipment enclosures were being removed
since there is now a published Control Cabinet standard and that the TF will include reference to this
standard within this clause.
The clause 6 TF has reviewed Annex A (informative) and has identified the material that is covered by
new guide C57.153. The TF Chair noted that there is some material from Annex A that needs to be
moved to the main body of standard C57.12.10 and that the will be working on doing so.
The WG Chair stated that there is still work to be done by the Task Forces so they would thus remain as
active Task Forces and that another draft of the clauses will be forthcoming for circulation and review.
New Business:
1. The Chair made a request for volunteers to perform an Editorial Review of the document in
advance of the next circulation of the draft clauses. Don Platts, Sue McNelly, Wally Binder, Ryan
Musgrove, and Shankar Nambi, Ewald Schweiger volunteered to take on this task.
2. Don Platts suggested that a short paragraph be complied to track the DETC decision that was
made during this meeting, possibly by the person who made the motion.
The WG Chair indicated that he will review the need for an electronic WG meeting between now and the
next Transformer Committee meetings in Atlanta in the spring 2016, potentially in the February-2016
time frame, based on the status of the Task Forces. If such meeting were to be scheduled the WG
members would receive notice at least 30-days prior.
The presentation slides from this meeting will be published to the website.
The motion to adjourn was made by Richard VonGemmingen and seconded by Don Platts. The motion
passed and the meeting was adjourned at 9:15 a.m.

WG Revisions to Installation of Power Transformers C57.93 Monday, November 02, 2015 1:45 MM – 3:00 PM
Memphis, TN Minutes of the Working Group Meeting
Chair Mike Lau called the WG meeting to order at 1:50 PM on November 02, 2015. 19 of 28
members were present, so a quorum was achieved. 91 guests also attended, for a total attendance
of 110. Fifteen (15) guests requested membership.
The start of the meeting was delayed due to technical difficulties with the projector, so approval
of the agenda and the spring 2015 minutes were bypassed.
Mike Lau reminded the working group that the PAR expires in 2016. A one-year PAR extension
will be requested after the chair evaluates the progress of the guide revision.
Wally Binder raised an issue regarding the safety warnings concerning confined space entry. The
meaning and intent of including lower explosive limits was discussed at great length. The need
to include typical confined space entry procedures was also debated.
Joe Watson made a motion to remove the warnings for confined space, including references to
LEL and all text discussing confined space procedures, and to add a generic statement that
company procedures and requirements established by regulatory authorities should be followed.
The motion was seconded by Alan Peterson. The motion passed unanimously.
A ballot resolution group was formed, comprised of Wally Binder, Patrick Rock, Ken Sullivan,
Alwyn VanderWalt, Scott Reed, Stephanie Denzer, Alan Peterson, Rick Simonelli, and the
working group officers.
Amotion to adjourn was made by Wally Binder, seconded by Derek Baranowski. The working
group meeting adjourned at 3:00 PM.

2. Chairman provided the WG a background regarding the work being done to harmonize the Tap-Changer
Standards and Application Guide between IEEE and IEC. General opinion from TF is that prospects are
very good to bring these two standards together as one. Clarification was made on the Harmonization
process by Jodi Haasz. Adoption of IEC 60214-1 standard allows for an Annex to be included to clarify
key differences between the two standards. This establishes a base for a joint revision by IEEE and IEC
in the future when the stability of IEC 60214-1 is within 4 years. It was published in 2014 with a
preliminary stability of 2019. Annex E of C57.131 will be included as an Annex in 60214-2, Application
Guide.
3. Comparisons were presented for the following specific clauses:
a. Clause 3 Definitions (Marten Almkvist)
b. Clause 4 Service Conditions (Jeffrey Golarz)

An n e x L Standards Subcommittee – Unapproved Minutes
November 4, 2015
Memphis, TN
Chair: William Bartley
Vice Chair: Kipp Yule
Secretary: Jerry Murphy
The Chair, William Bartley opened the meeting calling a show of members to establish quorum which
was met.
L.1 Meeting Attendance
The Standards Subcommittee met on Wednesday, November 4, 2015, at 4:35 PM. A show of hands
indicated only 22 of 46 members in attendance falling short of quorum at the starting time of the meeting.
Quorum was shortly achieved with arrival of additional members. Overall the attendance roll showed
there were 101 attendees, 27 members, 74 guests, including 13 that requested membership upon
tabulation of the circulated rosters and will be reviewed by the new chair once appointed. Bill then
requested a review of the Agenda; motion was made by Dan Sauer and seconded by Sanjib Som with
unanimous acclamation approving.
L.2 Approval of previous meeting minutes
The Chair asked if there were any comments or corrections to the previous meeting minutes of the Spring
2015 meeting in San Antonio, TX. There were no comments to the meeting minutes; a motion was made
by Dan Sauer for approval and seconded by Don Platts then the minutes for both past meetings were
approved by unanimous vote.
L.3 Chair’s Remarks
Bill summarized the recent activities of the Transformer Standards activity for the six-month period
March 2015 to October 30, 2015. In the last six months, two new Standards and one Revision were
approved by Standards Board. In this same period, the Standards Board approved seven PARs for new
standards or revisions to standards; five PAR modifications, and four PAR Extensions. The full Standards
Report is available on the Transformers Committee website at the following link:
http://www.transformerscommittee.org/meetings/F2015-Memphis/Minutes/F15-StandardsReport.pdf
Bill shared the following reminders with the subcommittee from the Administrative Subcommittee.
a. Agendas must be approved and recorded in minutes as do the minutes.
b. Standards procedurally must be approved by the SC to proceed to SA ballot. This is not a
technical review, but required to make advisement to all SC members.
Bill announced that this would be his last meeting and the Committee chairman would be appointing a
new chair before the next meeting.

L.4 Working group reports
L.4.1 Continuous Revision of C57.12.00
The purpose of this WG is to compile all the work being done in various TF/WG/SC’s for inclusion in
the continuous revision of C57.12.00 in a consistent manner. This WG coordinates efforts with the
companion Standard C57.12.90 so that they publish together.
The initial ballot for Standard C57.12.00 opened on 11-7-2014 and closed 12-30-14. There were a total
of 3 recirculation ballots that culminated in successful submittal to RevCom for the December 2015
meeting.
The unresolved issues are now being collected and will soon be sent to the various subcommittee chairs
so that they may take this on as future work in the working groups under their purview. (I have already
delegated material to Performance Characteristics Subcommittee).
Respectfully submitted by Steven L. Snyder, WG Chair, on November 4, 2015
Gary Hoffman offered to help expedite the process with the SA Standards Board.
L.4.2 Continuous Revision of C57.12.90-2006
The purpose of this WG is to compile all the work being done in various TF/WG/SC’s for inclusion in
the continuous revision of C57.12.00 in a consistent manner. This is a working group by committee.
There are no meetings held.
Summary
The new PAR was approved on June 15, 2011. It is valid until Dec 31, 2015.
Status
The initial ballot of the revised document was closed on Dec 31, 2014. There were 240 balloters and
268 comments. It received a 91% approval rate at that time. After many months of ballot resolution,
there have now been 4 recirculation ballots, and the approval rate is 94%. All comments have been
responded to. The document was finalized and submitted to REVCOM for their December meeting.
Hopefully it will get approval and be published this year.
Since this is a continuous revision document, there continues to be ongoing work in the various WG’s
and new material has already been submitted for the next revision. We should immediately take out a
new PAR next year.

L.4.3 Corrigenda for C57.12.70 – Steve Shull
Steve Shull called the meeting to discuss the Corrigenda to correct some of the figures in Annex A. An
invitation was sent to the previous working group members. Charles Switzer and Chuck Simmons
attended the meeting. Charles Switzer concurred that the figures called in the Corrigenda were
incorrect but he also pointed out that a number of the figures were incorrect. The group then spent the
remainder of the time, correcting the drawings. It was determined that a large meeting should be
schedule for the spring meeting 2016 to finalize this corrections with a larger group. Steve also stated
he would request a change in the PAR to reflect this additional work.
The chair would request a meeting room for spring meeting 2016 and would ask that those who would
like to join our group look for this in the agenda for the next meeting.

L.5 Old Business
• Kipp Yule, chair of a task force to develop a white paper that will capture the practice of WHAT
GOES WHERE was unable to attend the fall meeting. Jerry Murphy presented Kipp Yule’s
presentation including the S15 presentation of approach, and the first draft of the WGW Chart of
the Organization & Hierarchy of IEEE Transformer Standards and Guides.
• Steve Antoz chair of a task force to document the “unwritten rules” concerning C57.12.00 &
12.90; and how we can improve the process. Steve had no progress to report and solicited
volunteers from the subcommittee.
L.6 New Business
• Bill related this will be his last meeting as chair of the Standards subcommittee and that he would
be in full retirement. The Chair of a Subcommittee is appointed by the Chair of the Committee
with notification given to the Chair of the Technical Council. A new chair should be announced
ahead of the spring 2016 meeting in Atlanta. Tim Holdway has been appointed by the
Transformers Committee Chair with the concurrence of the immediate Past-Chair as the
Standards Coordinator.
• Dan Sauer brought to the subcommittee that standard C57.12.80 was inactive and many new
terms were not in the standard as well as others needing to be revised. Phil Hokinson presented a
number of terms related to renewable energy such as wind turbines and photo voltaic arrays were
not covered and other related issues should be considered. Phil especially recommended that the
definitions for Distribution Transformer and Power Transformers be revisited as the standard
currently reads step-up transformers are only Power Transformers. Bill agreed this standard
belongs to the subcommittee and asked for the subcommittee to consider what action should be

taken. Hemchandra Shertukde made a motion seconded by Dan Sauer that a task force be formed
to propose changes to revise the standard dealing with the terminology Phil suggested. Rick
Marek made a friendly amendment to make more of a general review to move forward with a
general revision. The motion was passed with unanimous proclamation by the subcommittee
members. Steve Shull offered support of the Distribution Transformers subcommittee and Bill
said the subcommittee would contact Joe Watson to invite the Power Transformers subcommittee
to participate also.

M.1 Meeting Administration
Introductions – The meeting was called to order at 11:00 AM in the Grand Ballroom of the Peabody Memphis
Hotel in Memphis, Tennessee. Introductions were made and sign-in sheets were routed.
Quorum – The members were listed on the screen and by a show of hands, it was determined that there was a
quorum with 14 of the 18 members in attendance.
Approval of Minutes – The minutes from the Spring 2015 meeting in the San Antonio, Texas were approved with
the changes noted in the working group reports below. They were motioned for approval by Brian Klaponski and
seconded by Al Traut. The subcommittee approved these without opposition.
Members and Guests --There were 14 members and 19 guests in attendance. Their names can be found in the AM
system.
The chairman, Dan Mulkey, asked that as reports are read that each group state where they are relative to completing
work on their PARs.
The chair mentioned that Greg Anderson has reminded everyone to include details of the next meeting in the
minutes of the current meeting.
We have also been asked to submit a second document along with the meeting minutes that summarizes why
changes to the spec were made. For example, he said he would like to see subsurface transformers painted white
instead of black. The reason which is enhanced visibility would be the reason and would be in a companion
document. The thinking is that it will cut down on the comments in the ballots. Brian Klaponski stated that he feels
it is an unnecessary burden and is not in the procedures. The chair stated that it is probably headed there.

mentioned that we should be fine to meet that deadline. We would like to send to ballot in the fall
meeting of 2017.
Approval of Agenda – Motion: Justin Pezzin, Second: Jermaine Clonts, unanimous
Approval of Minutes – Motion: Bill Wimmer, Second: Christopher Sullivan, unanimous
Old Business
Review draft changes from last meeting. Section 5.6 – We pulled in the table from 12.20 on minimum
impedances.
Dimensions discussion – Jermaine stated that with regards to increases in efficiency per DOE that the maximum
overall dimension should be 40”. Giuseppe stated that his company will still have to specify 36” due to existing
space constraints of their manholes. Brian asked if there was a standard on manhole widths; general consensus
is that all users have different sized manholes that they use. Giuseppe asked about dimension differences due to
changes in BIL or voltage levels.
Motion made by Jermaine to change the overall dimension for 250 kVA from 36” to 40”. Seconded by Dan
Mulkey. Giuseppe would like to see a breakdown in voltage class. Jermaine stated that his analysis was a worst
case (i.e. 35 kV) scenario that led to the 40” overall diameter. Vote results: 5 yes, 6 no; does not pass.
Suggestion was made by Paul Chisholm and Brian Klaponski to perform a survey of the users of this size
transformer and find out what limitations that they have for diameter and height for the different voltage classes.
Do we need to have diameter and height dimensions in the spec? Al is going to take on the task of getting the
survey to our user and manufacturer base for input. Make sure that the survey includes the question about what
clearance between the overall diameter and manhole opening is needed by users.
We need to verify with Lee Mathews regarding the cable standard references and if they are up to date (ICEA).
Secondary terminal table updated with 250 kVA. Suggestion made by Giuseppe to update table with voltage
class information. Task Force to help with this: Jermaine Clonts, Bill Wimmer, Giuseppe Termini.
Horizontal Transformers – Dan Mulkey discussed PG&E’s specification on horizontals. He explained the
drivers behind PG&E going to these types of transformers. The main benefit is for operation of the elbow and
secondary connections. Another benefit is that you won’t be on top of the tank trying to operate, which also
helps with Arc Flash Hazards. Al – After reviewing Dan’s work, does the WG want to pursue including
horizontals in this standard? We might want to include this work in an Annex so that it is not considered to be a
minimum requirement. There was no vote but it seemed like there was general consensus regarding the
inclusion of horizontal tank transformers.
New Business
A comment was made by Brian Klaponski that we may have to include requirements on specific tank materials
like we have in C57.12.24 and C57.12.40.
Chris Sullivan stated that we need to discuss how we are going include pressure relief content that will be
published in C57.12.39.
Adjourned at 10:45 am.
In addition to his minutes, Al mentioned that he had a hard time achieving quorum since there is a task
force for bushings that meets at the same time and some of his members also want to go to that meeting.
He will try to get his meting time changed

Giuseppe Termini, Chairman; George Payerle secretary
Revision due date: 6/17/2019
PAR Approval Date: 11/9/2011
PAR Expiration Date: 12/31/2015
The meeting was called to order at 9:30 AM, November 2, 2015 in the Grand Ballroom D of the
Peabody Memphis Hotel in Memphis, TN. Introductions were made and an agenda was presented. The
meeting was attended by 17 members and 47 guests. Membership stands at 21, and with 17 members
present, there was a quorum. Seven (7) guests requested membership. The Chairman stated that
attendance at 3 consecutive meetings was necessary for membership. Any member missing 2 meetings
in a row would be dropped unless the Chairman was notified with a valid justification for missing the
meetings.
George Payerle acted as recording secretary. Minutes from the previous meeting in San Antonio, TX
were presented. Justin Pezzin made a motion to approve the minutes, Dan Mulkey seconded it, and the
motion was approved unanimously.
The Chairman stated that the PAR will expire on December 31, 2015. A request for a two year PAR
extension has been submitted to NESCOM of the IEEE-SA for review and approval during their next
meeting on December 7th.
The Chairman discussed the ballot status of Draft D5. There are 89 individuals registered to ballot the
draft. As of November 1st, 30% of those individuals had voted. The approval rate so far is 96%. There
is only one disapproval vote with 3 comments. 75% participation is required to successfully ballot the
draft. Forty (40) additional responses are required to achieve the 75% threshold. The ballot will closes
on November 21, 2015, and the Chairman encouraged those who registered should vote.
The Chairman stated that prior to submitting Draft D5 for ballot, the draft was sent to the Mandatory
Editorial Coordination (MEC) staff for review. Two sets (Section I and II) of comments were received
from MEC staff. Comments from Section I were incorporated in Draft D5 prior to ballot. Comments in
Section II must be satisfied prior to standard recirculation.
The Chairman recommended the formation of a ballot resolution task force made up by 5 individuals to
address comments received from the balloting process. The Chairman suggested that the task force
would be made up by 2 end-users, 2 producers, and one interested individual. Cory Morgan from
Erversource, who was not in attendance, agreed to be part of the task force, and along with the
Chairman will represent the end-users. Cory also agreed to lead the task force. Brian Klaponski and
Paul Chisolm agreed to represent the producers and Dan Mulkey agreed to be the fifth interested
member. The purpose of the task force will be to resolve the comments received from balloting process.
The task force will then report resolution of the comments to the WG members for final review and
approval. Brian Klaponski made a motion that this task force be created, Mike Hardin seconded and the
motion was approved unanimously.
Brian Klaponski stated that he did cast a vote on Draft D5 because of additional comments he had on
several sections of the standard. The comments are listed below:
Section 7.5.1.3, Material thickness - Table 6 contains inconsistency in the way inches and
millimeters are expressed. This could be a possible rounding issue.
Section 7.3.1, Tap Changer – The primary tap ratings referenced in Table 5 seems to be
ambiguous.
Annex M
Page 4 of 8
Section 7.4, Nameplate – The impedance statement in this section, along with the impedance
description shown on the Note under Table 3 of Section 5.5, seems to be ambiguous.
Section 7.5.4, Other Material - The wording ‘similar to bronze’ is in the wrong sentence.
Section 7.5.10, Finish – The coating standard C57.12.32 refers to the 2002 revision of that
standard. The year should not be included when referring to a standard.
Section 7.6, Components for primary cable system - The words ‘1000 A’ should be 10 kA.
Section 8.2, Installation – The “angle of tilt” is not well defined for the manufacturers. It was
suggested that a minimum angle of tilt be listed.
The Chairman stated that the comments received by Brian Klaponski should be submitted as part of the
ballot process and will be addressed by the ballot resolution task force.
The Chairman stated that he received comments from various individuals regarding difficulty to sign up
into the PES system for the ballot invitation, and then to actually ballot. Erin Spiewak, from the IEEE-
SA addressed the WG to explain how to sign up for the ballot invitation process and cast a ballot. Erin
also stated that to ballot, one must be an SA member or pay a onetime fee but there is no requirement to
belong to IEEE or attend meetings.
The meeting was adjourned with the next meetings scheduled for March 2016 in Atlanta. Bill Wimmer
moved and Anil Dhawan seconded the motion to adjourn.

The Chair also presented the contents of the Annex: “Coordination of Bushing Selection and
Application” proposed for inclusion in the standard.
Larry Dix expanded on the thermal calculation and explained the creation of the chart shown in the
proposed Annex.
Jeremy Sewell made a motion to add a mathematical equation that derives the thermal graph shown in
Figure 1 of the Annex. George Payerle seconded the motion and the motion was approved
unanimously.
George Payerle made a motion to accept the Annex as amended and add it to the current draft of the
standard. Tas Taousakis seconded the motion and the motion was approved unanimously.
Annex M
Page 5 of 8
Larry Dix explained the reasons to add the Annex to the standard. Primarily, the reason of the Annex is
to address the separation of the elbows connection with bushings during a fault condition outside the
transformer.
The Chair stated that the comments received from John Rossetti have been already handled in our
standard except that John’s proposal on the protector height did not fit with many other users so it will
not be incorporated.
Item 10 of the previous meeting in San Antonio recommended the inclusion of stainless steel
requirement for tank material. The Chair made a proposal of a clause to do this. In the discussion Bob
Kinner (material specialist) explained the basic difference of 304L versus 316L stainless steel. Bob
volunteered to look into the specific benefits of 304L versus 316L in regards to weld stress cracking
and will report out at the next WG meeting. Also the Chair explained that 316L had an advantage in a
chlorine environment and Bob Kinner concurred.
Tas Taousakis gave a general discussion from an end-user point of view on corrosion effects on carbon
steel tanks and its adverse effects. Tas asked if manufacturers had issues constructing a tank with
stainless steel material and the response was no.
Mark Faulkner suggested that painting may be an issue with 316L stainless steel tanks. The Chair
suggested that painting should not be addressed in the standard as network transformer manufacturers
all had methods to properly paint stainless steel. The Chair also explained about emissivity issues
associated with stainless steel tanks that are not painted and why from a cooling standpoint a painted
stainless steel tank is preferred for cooling issues.
Tom Holifield asked if 316L stainless steel material applied to accessories such as flanges. The Chair
stated that yes 316L stainless steel does apply and also that the material requirements for accessories are
covered in Section 5.2.2.
Liz Sullivan made a motion to add “316L” between the words: austenitic and stainless steel in Section
5.2.2. The motion was amended by Liz to: “300 series” between the words: austenitic and stainless.
Alex Macias seconded the motion and the motion was approved unanimously.
Dan Mulkey made a motion to include stainless steel material requirements when the transformer is
installed in a corrosive environment, specifically Dan motioned to include the following statement
follwing Table 5 of the standard. It would include a new Table 6.
As an alternate to using copper-bearing steel, some users may specify a stainless steel tank enclosure
for applications where a transformer will experience an especially corrosive environment (such as
frequent or continuous submersion in salt water). When stainless steel is specified, it shall be Type
316L with minimum material thickness as shown in Table 6.
Table 6—Stainless Steel Minimum material thickness

Mark Faulkner seconded the motion and the motion was unanimously approved.
Annex M
Page 6 of 8
The Chair asked the WG if a PAR extension should be submitted to continue working on the standard
or take the standard to ballot. There was no response to his request, therefore the Chair made a decision
to take the present draft as amended by this meeting to ballot on the basis that this specification is a
living document and further improvements can be made to this standard in future revision.
The meeting was adjourned at 12:18 pm with the next meeting set for Atlanta, GA in March 2015.
M.2.4 C57.12.44 Working Group Report – Secondary Network Protectors
Bill Wimmer, Chairman, Mark Faulkner, Secretary
Revision due date: 12/31/2024
PAR Approval Date: 3/26/2015
PAR Expiration Date: 12/31/2019
The meeting was called to order at 1:45 PM, on Monday, November 2nd 2015 in the Grand Ballroom
D of the Peabody Hotel in Memphis, Tennessee. Introductions were made. A short discussion on
establishing membership in this new working group was made. A total of 17 individuals attended the
meeting. Membership stands at 10 members and there was a quorum.
Bill Wimmer presented the meeting agenda to the WG for review and acceptance. Ed Bertolini
motioned to approve the meeting agenda as presented, Dan Mulkey, Alex Macias seconded the motion,
the motion was approved unanimously.
New Business
The WG discussed what changes should be considered in the next revision of C57.12.44.
The working group discussed the section 8.2 which describes details on network protector fuses. The location
of which appears to be better suited to be included in Annex B. The section was re-located.
Dan Mulkey suggested change to average melting curve should be slower than network protector and to strike
under no circumstances. The wording was fuses with a min. melt curve faster than the network protector relay
tripping response, should not be used. Dan Mulkey motion, Ed Bertolini second the motion.
Comments by Lee Welch were received and review started.
Generation- changes made
Network Protector designed and tested in accordance with the standard, in particular with 5.2, are intended to
be applied to a system with power normally flowing only from the high voltage side of the transformer that
supplies a secondary network.
Special precautions must be taken with generation or energy storage on a secondary network that could result
in reverse power flow as this will create an undesired and possibly unsafe condition.
Dan Mulkey motioned and Mark Faulkner seconded, carried unanimously.
Accepted IEEE STD. C57.12.00-2010 as normative reference.
Continuous current thermal test
Left temperature range 10C and 40C as stated versus 4.1.2 for realistic representation of thermal test
conditions.
Annex M
Page 7 of 8
Table 1- Temperature rise- Motion by Mark Faulkner to add C to temperature class, second by Alex Macias.,
approved unanimously.
Test Conditions
Rejected Lee Welch Comment for conductor versus copper bus bar. Left copper bus bar in place.
Add thermal term to insulating panel per Lee Welch comment. Motion by Alex Macias, Dan Mulkey second.
Motion carried.
Changed thermocouples to temperature sensors in multiple places.
The meeting was adjourned and the next meeting set for Memphis, TN in November 2015.
M.3 Old Business
Brian stated that he thought 4 years was insufficient time for a PAR since the balloting process consumes a full year.
In addition, there is now the issue of public comment on anything going to ballot after July 1 2015. This can
potentially require even more time. Dan stated that a workaround is available. A study group can be assembled to
work on a standard. Then when the work is well underway, a PAR can be requested. Brian made a motion to
petition the transformers committee to request a change to 5 years for a PAR. George seconded. The motion passed
unanimously.
M.4 New Business
M.4.1 Working group C57.12.57
The chair stated that a manufacturer had requested that working group C57.12.57 for dry type network
transformers be resurrected. However, the person who asked was not at the meeting. A discussion
followed and the following points were made: David Walker of ABB said that they have made a few
ventilated dry type network transformers recently but they are not submersibles. Larry Dix commented
that someone is making submersible dry types that are not ventilated. Brian suggested we could poll
the users. Dan Mulkey said that PG&E has 1200 networks and only about 40 are dry type but their use
is increasing. Mike Thibault said PG&E is using dry types in high rise buildings. Martin Navarro said
that Siemens Brazil makes a cast coil submersible transformer. It is a patented product. He has 3 units
in the network in Sao Paolo. In the end it was decided that this subcommittee would not take any action
at this time.
M.4.2 SC Scope
The chair stated that we have been requested to change the wording of the scope of our subcommittee.
Currently it is ‘Underground Transformers and Network Protectors’. Various possibilities were
discussed. Brian made a motion that a small task force of 3 people – Dan Mulkey, Larry Dix, and Jim
Dorsten be formed. They will discuss and come to a conclusion on a new scope which they will then
share with the rest of the committee, George seconded the motion and it passed unanimously.
There was discussion about whether the currently named underground transformer and network
subcommittee be incorporated into the distribution transformer subcommittee. After some discussion
by a show of hands it was unanimously decided to keep the underground group as a separate
subcommittee.
Annex M
Page 8 of 8
M.4.3 Misc
There was one person who suggested re-ordering the UTNP WG meetings so they would be more
convenient for his schedule. After some discussion it was decided that making a change would make it
impossible for other people to make all the meetings they needed to attend so we will leave the schedule
as it is.
Due to personal reasons, Bill Wimmer is resigning as chair of the C57.12.44 Working Group. Mark
Faulkner has agreed to accept the position. Alex Macias will be his secretary.
Brian wanted to publicly thank Bill Wimmer for all his work in C57.12.44. Bill will be at the spring
meeting so he will be recognized at the awards luncheon at that time.
Brian also brought up the topic of safety. He said that in his visit to ABB Alamo he was very impressed
by their safety procedures and thinks we should find a way to make it a strategic agenda in our
standards.
M.5 Adjournment
The meeting was adjourned at 12:30 PM with the next meeting set for Atlanta, Georgia on March 23, 2016.
