INTRODUCTION

DANGER

Hazardous high voltage is present at the line terminalsof the bushings on the cover of the regulator.

Will cause severe injury or death.

To prevent:

Isolate the regulator before servicing.

Type JFR voltage regulators are routinely equipped with linebushing terminals per the following criteria.

Clamp type terminals for use through 668 ampere arecapable of accepting an aluminum or copper conductor.

Tank grounding provision consists of a 0.5-13NCtapped hole in a steel pad for regulators rated to 300amperes. Above 300 ampere ratings, a copper-facedpad with two 0.5-13NC tapped holes is provided.

Type JFR regulators are commonly installed using anyof four electrical configurations.

One regulator in single-phase application. (Figure 4D)

Two regulators in open delta on a three-phaseungrounded system. (Figure 4B)

Three regulators in closed delta on a three-phaseungrounded system. (Figure 4C)

Handling. Type JFR regulators are designed to be liftedeither by a forklift at the base or by use of hangar bracketson the side of the tank. Each JFR regulator is providedwith either 2 or 4 lifting hooks on the side of the tank. Thenumber of hooks has been established to provide a mar-gin of safety on lifting when all hooks provided are used.

PHYSICAL CONSIDERATIONS

Location. Type JFR regulators are designed for outdoorinstallation. Any regulator may be platform or pedestalmounted. Regulators provided with hangar brackets aresuitable for pole mounting. When the regulator is to beinstalled in a substation on a pedestal it is recom-mended that a minimum elevation to the live connectionbe established, as required by applicable codes.

Elevation. When the regulator will be used at an elevationabove 1000 meters (3300 feet) the kVA rating must bereduced to assure operating temperature limits are notexceeded.

•

•

Falling unit can cause severe injury or damage.

To prevent:

Do not use cover lifting eyes tolift complete unit.Cover lifting eyes are for untanking of regulator only.

Lift complete regulator by using all side tank hooks.

WARNING

•

For air cooled (OA) rating, derate kVA rating 0.4% for every100 meters (330 feet) elevation above 1000 meters.

For forced air cooled (FA) rating, derate kVA rating 0.5% forevery 100 meters (330) feet elevation above 1000 meters.

PROTECTIVE MEASURES

Bypass Arrester. All JFR regulators are equipped with aproperly sized arrester, connected externally between the 'S'and 'L' line terminals. The arrester is provided to protect theseries winding of the regulator from line surges. Of itself,the bypass arrester does not provide lightning protection forthe regulator.

Lightning Protection. The number of lightning arresters usedwill be a judgmental decision on the part of the user, consid-ering such factors as isokeraunic level and degree of risk ofdamage to be accepted. The minimum recommended light-ning protection consists of a properly sized arrester betweenthe 'S' or 'L' bushing and ground on a single phase or a wyeconnected system. A delta connection system requires theuse of two arresters to accomplish minimum protection lev-els. Additional protection can be obtained with the use ofarresters at both the 'S' and 'L' terminals in single phase orwye systems and on all three terminals on a delta system.

For best results, install lightning arresters on the mountinglugs adjacent to the bushings near the top of the tank. Thelugs are 0.5 - 13NC located on 2.5 inch centers. Ground thearrester(s) and the regulator tank solidly to the same groundconnection. Be careful to keep the ground lead connectionsas short as possible.

Thru Fault. Type JFR regulators are rated under condition ofthru-faults for twenty five times the OA rated current for 2seconds or 40 times the OA rated current for 0.8 second to amaximum of 20,000 amperes rms symmetrical. The faultcurrent may be asymmetrical to the extent that the peak ofthe first current loop is equal to 2.26 times the rms value ofthe current wave.

The user is advised to provide for additional source imped-ance, bus sectionalizing or other means of limiting the avail-able thru-fault current if these criteria are exceeded at theinstallation

CONTROL CONNECTIONS

Many regulators can be used at several different nominalsystem voltages. It is therefore necessary to assure that theregulator is properly connected at the 19 pin upper terminalblock for the system voltage on which the particular regulatorwill be used.

For this purpose, it is necessary to use the nameplatedrawing and control diagram found in the control enclosure.

Refer to the Nameplate Diagram. A column is indicatedto connect lead P2 to P( ), based on the applicablesystem voltage. The control diagram will aid in identifi-cation of the appropriate pin on the 19-pin terminal block.

1.

Depending on the regulator, there may be a secondcolumn indicating that lead U2 is to be connected toU ( ). The same procedure is followed.

2.

For regulator equipped with fans for forced-aircooling, another set of connections will be shown.

3.

Matters specifically relating to the Accu/StatTM control used in conjuntions with theregulator are not included in this manual.Refer to the appropriate control instructionmanual.

PLACING THE REGULATOR IN SERVICE

The following checks will be useful in assuring the regulatoris ready for use. The list cannot be all inclusive; careful at-tention on the part of a qualified operator remains impera-tive.

BEFORE CONNECTING

Check oil level at oil sight window. If low, add sufficientoil (ASTM D-3487 Type II) to bring level to that desired.

Check dielectric strength of the oil per ASTM D-877. Iffound to be below 24 kV, filtering should be accomplishedand additional testing of oil integrity is justified. Note:This is not necessary if regulator is being installed im-mediately upon receipt from the factory.

Take power factor reading of all bushings (common)against ground (tank). Reading should be less that 2.0%.

Verify from the nameplate that the unit is connected forthe proper output voltage, motor voltage and control panelvoltage.

Assure that the regulator is on the neutral tap position.This should be accomplished by observing the positionindication pointer and by powering the control from a120V external source and observing the NeutraliteTM tobe illuminated.

Identify 'S', 'L' and 'SL' bushings on the cover. Make elec-trical connections per the appropriate installation dia-grams, page 4, first connecting 'SL' bushing.

Set Vari-AmpTM limits on position indicator, if necessary.See Page 11.

Set Accu/StatTM Control as desired. See Accu/StatTM

instruction manual

SWITCHING THE REGULATOR"ON THE LINE"

It is absolutely imperative that the regulator be on the neutraltap position before switching the regulator on the line.

CONNECTING

High pressure or mechanical failure due to improper by-pass operation can cause death, severe injury or damage.

To prevent:

Energize regulator only with regulator on neutral tap posi-tion.

Follow instructions:

1. Make certain regulator is in neutral (N) position.2. Turn voltage source switch to "OFF".3. Remove power fuse.4. Close, sequentially, the source and load switches.5. Open the bypass switch.6. Visually observe that bypass circuit has opened.7. Replace power fuse.8. Place voltage source switch to normal.

WARNING

CHECKING REGULATOROPERATION

Turn the transfer switch to MANUAL.

Run the tapchanger in the lower direction, at least untilthe control is observed to go out of band "LOW".

Turn the transfer switch to AUTO. After a time delay, theregulator will return to an "IN" band condition.

Turn the transfer switch to MANUAL.

Run the tapchanger in the raise direction, at least untilthe control is observed to go out of band "HIGH".

Turn the transfer switch to AUTO. After a time delay, theregulator will return to an "IN" band condition.

REMOVING THE REGULATOR FROM SERVICE

WARNINGHigh pressure or mechanical failure due to improper by-pass operation can cause death, severe injury or damage.

To prevent:

Bypass regulator only with regulator on neutral tap posi-tion.

Follow instructions:

REMOVING THE REGULATORFROM THE LINE

In order to remove a regulator from service without droppingload, it is imperative that the regulator be on the neutral posi-tion. The system must first be de-energized (load dropped)before removal. If the regulator being removed is in a closeddelta bank, it is necessary to bypass and isolate all regula-tors in the bank. The routine removal procedure is essen-tially the reverse of the procedure used to place the regulatoron the line.

Run the regulator under normal voltage source to theneutral position, as revealed by the tap position indica-tor.

1.

Confirm via the NeutraliteTM indicator that the regula-tor is on neutral. If the independent checks of the po-sition indicator and NeutraliteTM indicator do not con-firm the neutral position, bypassing must not be at-tempted. In such event, de-energize the system to re-move the regulator from service.

2.

After assuring that the regulator is on neutral, closethe bypass switch.

Open, sequentially, the load and source switches.

3.

4.

5.

6. Exercise appropriate care in the removal of theregulator. High voltage will still be present at thebypass witch and the source and load switchterminals. Remove the ground connection last.

(b.) For a closed delta connection, be sure all regula-tors in the bank are bypasses and isolated.

(a.) For a single phase or grounded wye connection,make sure that the high voltage disconnect switchesare opened.

MAINTENANCE

GENERAL INSTRUCTIONS

Failure to properly maintain the regulator can result in se-vere personal injury and product failure. The instructionscontained herein should be carefully reviewed, understoodand followed. The following maintenance procedures shouldbe performed regularly:

1. Operational checks

• Control performance

• Tapchanger performance

• Vari-AmpTM limit performance.

2. Periodic inspection

• Oil sample

• Oil oxidation inhibitor addition

• Contact wear

• Fans

This checklist does not represent an exhaustive survey ofmaintenance steps necessary to ensure safe operation ofthe regulator. Particular applications may require further pro-cedures. Should further information be desired or shouldparticular problems arise which are not covered sufficientlyfor the purchaser’s purposes, the matter should be referredto the local Siemens sales representative.

When powered, dangerous voltages are present in the equip-ment that can cause severe personal injury, death, and prod-uct failure. Always de-energize and ground the equipmentbefore maintenance requiring access to high voltage parts.

The use of unauthorized parts in the repair of the equipment,tampering by unqualified personnel, or faulty repair and ad-justments will result in dangerous conditions which cancause severe personal injury or equipment damage. Followall safety instructions contained herein.

OPERATIONAL CHECKS

Basic regulator operation can be checked while the regula-tor remains in service. Simply provide means to observe theoutput voltage (such as a voltmeter connected at the testterminals).

• Observe that the voltmeter reads the voltage level settingrequired by the control, to within one-half of the band-width tolerance. Note 1: The control must be “in” band.Note 2: Line drop compensation must be set to zero if theregulator is carrying load.

• Run the tapchanger several steps in one direction in themanual mode until the output voltage is outside of thebandwidth. Return the control to automatic mode. Afterthe predetermined time delay, the tapchanger motor willbe observed to return the output voltage in-band. Repeatthis operation, running the tapchanger in the oppositedirection.

• Check the Vari-AmpTM limit switches by attempting to runthe tapchanger beyond the position to which the switchesare set. The limit switches should function to open thecircuit. Note: If the limit switch is set at the maximum 10%range and fails to function, the tapchanger will stall againsta mechanical stop. The motor is designed to stall con-tinuously without damage

CAUTION

WARNING

Operation of the regulator at extreme tap positionscould produce a line voltage above or below desiredoperating limits at the load.

To prevent:

Operate the regulator only to judiciously determinedvoltage extremes.

Regulator may have High Internal Pressure. Cancause serious personal injury or death, or damage tothe regulator.

To prevent:

Use pressure relief valve to vent regulator beforeuntanking.

om

A sample of oil from the regulator should be subjected todielectric breakdown test, per ASTM D-877. It is recom-mended that oil testing less than 24 kV be filtered. Othertests, especially Neutralization Number, Interfacial Tensionand Power Factor are also useful and may be preferred byparticular users.

The oxidation inhibitor in the oil will be depleted over a pe-riod of a few years and should be replaced. The inhibitor is2, 6-ditertiary-butyl-para-cresol (DBPC) at a concentrationlevel of 0.2 to 0.3%.

The time interval between internal inspections will dependupon frequency of tapchanger operation and the load on theregulator. Regulators subjected to numerous overloads anda high load factor may require more frequent inspectionsthan those carrying normal loads. While internal inspectionis not a necessity, preventive maintenance inspections willhelp assure the continuity of service.

PERIODIC INSPECTION

If cover top cap is removed, make certain the cap is properlysealed when replaced on cover. Siemens recommends ap-plying pipe sealant (Loctite PST or equivalent) around thethreads of the adapter. Furthermore, it is recommended thatthe seal be tested by applying 5 psig pressure through thepressure relief valve fitting for 5 minutes, with no loss inpressure. Failure to assure seal may allow moisture to bepulled into the unit during a cool-down cycle.

Remove the regulator from service as described on Page 7.

Place the regulator in a position where energizedoverhead lines will not interfere.

1.

2.

Operate pressure relief valve to vent regulator beforeuntanking

3.

Remove the three mounting bolts holding the controlbox onto the main tank.

4.

Loosen all cover bolts and turn outward 180 degrees.5.

The regulator can now be pulled from the main tankby the cover lifting eyes.

6.

When inspecting, check to be certain all hardware and con-nections are tight. The principal point of the internal inspec-tion will be the condition of the arcing contacts on thetapchanger. Since numerous factors influence the rate ofcontact tip wear, no one criteria can be stated to recom-mend when a contact should be changed.

The following figure shows the possible condition of con-tact wear after a period of operation. If a contact surface hasburned down so that only a 1/8 inch wide line contact arearemains, the contact will probably be giving adequate ser-vice at low contact temperatures, but much further deterio-ration will probably result in decreased spring pressure andpossibly faulty operation. Therefore, the contact should defi-nitely be replaced. (See Figure in next column.)

Contacts, both movable and stationary, show normalburning and wear after 1,500,000 operations. If for anyreason A1 dimensions exceeds 4/5 of A, the stationarycontact should be replaced.

SEALED REGULATORS WITHPRESSURE RELIEF VALVE

To untank a JFR regulator, proceed as folllows:

The fans used for cooling (on some regulators) require aminimum of attention. Fans with plain sleeve bearings orOil-Lite sleeve bearings should be oiled at least once ayear with a good grade of SAE 10-W mineral engine oilwhich does not thicken in cold weather. Oil must be addedto sleeve bearings before starting motor for the first timeafter installation.

Fans equipped with ball bearing motors are packed withgrease before shipment and should be greased at leastonce a year with a soda-soap, ball-bearing grease of me-dium consistency furnished by a reliable supplier.

For fans that are seldom used, the frequency for greasing oroiling may be less than outlined above, but it is recom-mended that this lubrication be placed on a yearly schedule.It is often possible to determine by inspection whether lubri-cation is required.

SPECIAL FEATURES

The Accu/StatTM control panel is hinged and may be re-moved completely from the regulator control box by remov-ing the wing nuts on the polarized jack plug and pulling thejack from its fixed portion. This will automatically de-energizethe control. It is not necessary to bypass or de-energize theregulator to remove the control.

A spring-loaded shorting bar in the plug automatically shortcircuits the current transformer secondary when the jack isremoved.

The Accu/StatTM control may beremotely mounted. Remotecable is available in standardlengths of 18, 25 and 30 feetincorporating oil and moistureresistant, color-coded conduc-tors.

REMOTE MOUNTINGOF CONTROLEQUIPMENT

VARI-AMPTM POSITION INDICATOR

The Vari-AmpTM feature provides a method of operating theregulator at increased load by decreasing the range of op-eration. It provides operator flexibility by allowing the range ofregulation to be adjusted in 1 1/4 percent increments. Thevarious regulation ranges together with the correspondingcurrent capacities for standard regulators are listed on page11. All that is necessary to adjust the range of regulationanywhere from ±5 percent to ±10 percent is to turn the ad-justing knobs until the proper range of regulation is shownon the side of the position indicator. The upper and lowerlimits need not be the same.It is not necessary to remove the regulator from service tomake this adjustment. The switches are, however, in themotor power circuit so the motor should not be running whilethe switches are being set.

OPERATION AT LESSTHANRATED VOLTAGE

JFR regulators may be operated at lessthan the voltage for which they were de-signed. All system voltages for whichcontrol system taps have been providedare shown on the nameplate. When thisis to be accomplished it may be neces-sary to reconnect particular leads at theupper 19-pin terminal block as illustratedon page 5. When operating the regula-tor at reduced voltage it must be notedthat the regulator carries a maximumcurrent rating which rules regardless ofthe voltage (see table at right). It maytherefore be necessary to operate theregulator at less than its nameplate kVArating.

Units with catalog number starting with10 are self cooled11 are forced-air cooled

Regulators can be modified at factory for50 Hz operation with appropriate deratingof voltage.

SPECIAL FEATURES

Certain regulators may be equipped for forced-air coolingand include fans mounted on the radiators. The fans areusually automatically controlled by means of the change inoil temperature (see Connection Diagram). The thermom-eter located in the top transformer oil contains two identicalswitches which control fan operation when fan controlswitch is in “Auto” position.

The switches are normally set to start the fans at 65°C andto stop them at 55°C top oil temperature, but may be ad-justed plus or minus 5°C.

A thermal overload relay is mounted on each fan motor. Anyfan that develops trouble will be automatically disconnectedfrom the line without affecting the other fans of the system.One fan can be removed from the radiators without affectingthe operation of the others. When fans are out of service,care must be exercised to prevent overloading the regulator.Fan should be removed and replaced carefully to preventdamage to the radiators.

FORCED AIR COOLING SUBBASE ASSEMBLY

Subbase assemblies are available in 4-inch high incrementsfrom 21 through 49 inches for most JFR regulators. Theproper height is selected by picking the elevation that willprovide required clearance from foundation to the live part ofthe regulator bushing.
