Section 2 Starting up
2.1 Factory and site acceptance testing
Testing the proper IED operation is carried out at different occasions, for example:
• Acceptance testing• Commissioning testing• Maintenance testing
This manual describes the workflow and the steps to carry out the commissioningtesting.
Factory acceptance testing (FAT) is typically done to verify that the IED andconfiguration meets the requirements by the utility or industry. This test is the mostcomplex and in depth, as it is done to familiarize the user to a new protection or toverify a new configuration. The complexity of this testing depends on several factors.
• New IED type• New configuration• Pre-configured• Modified existing configuration
Site acceptance testing (SAT or commissioning testing) is typically done to verifythat the new installed IED is correctly set and connected to the power system. SATrequires that the acceptance testing has been performed and that the applicationconfiguration is verified.
Maintenance testing is a periodical verification that the IED is healthy and hascorrect settings depending on changes in the power system. There are also othertypes of maintenance testing.
2.2 Commissioning checklist
Before starting up commissioning at site, check that the following items are available.
• Single line diagram• Protection block diagram• Circuit diagram• Setting list and configuration• Crossed Ethernet cable (CAT 5)• Three-phase test equipment
1MRS756801 A Section 2Starting up
630 series 11Commissioning Manual
• PC with PCM600 installed along with the connectivity packagescorresponding to the IED used
• Administration rights on the PC to set up IP addresses• Product documentation (engineering manual, installation manual,
commissioning manual, operation manual, technical manual andcommunication protocol manual)
2.3 Checking the power supply
Check that the auxiliary supply voltage remains within the permissible inputvoltage range under all operating conditions. Check that the polarity is correct.
2.4 Energizing the IED
2.4.1 Check the IED operationCheck all connections to external circuitry to ensure that the installation was madecorrectly, before energizing the IED and carrying out the commissioning procedures.
Energize the power supply of the IED to start it up. This could be done in numberof ways, from energizing a whole cubicle to energizing a single IED. The IED timemust be set. The self-supervision function in the Main menu/Monitoring/IEDstatusorMain menu/Monitoring/Internal events menu in LHMI should also bechecked to verify that the IED operates properly.
2.4.2 IED start-up sequenceThe following sequence is expected when the IED is energized.
• The green Ready LED starts instantly flashing and the ABB logo is shown onthe LCD.
• After approximately 30 seconds "Starting" is shown on the LCD.• Within 90 seconds the main menu is shown on the LCD and the green Ready
LED shows a steady light, which indicates a successful start-up.
The start-up times depend on the size of the applicationconfiguration. Application configuration with less functionalitymeans shorter start-up times.
If the green Ready LED continues to flash after start-up, the IED has detected aninternal error. Navigate via Main menu/Monitoring/IED status to investigate thefault.
Section 2 1MRS756801 AStarting up
12 630 seriesCommissioning Manual
2.5 Setting up communication between PCM600 andthe IED
The communication between the IED and PCM600 is independent of the usedcommunication protocol within the substation or to the NCC.
The communication media is always Ethernet and the used protocol is TCP/IP.
Each IED has an Ethernet interface connector on the front and on the rear side. TheEthernet connector can be used for communication with PCM600.
When an Ethernet based station protocol is used, PCM600 communication can usethe same Ethernet port and IP address.
For the connection of PCM600 to the IED two basic variants have to be considered.
• Direct point to point link between PCM600 and the IED front port.• Indirect link via a station LAN or from remote via a network.
The physical connection and the IP address must be configured in both cases toenable communication.
The communication procedures are in both cases the same.
1. If needed, set the IP address for the IEDs.2. Set up the PC or workstation for a direct link (point to point), or3. Connect the PC or workstation to the LAN/WAN network.4. Configure the IED IP addresses in the PCM600 project for each IED to match
the IP addresses of the physical IEDs.
Setting up IP addressesThe IP address and the corresponding mask can be set via the LHMI for eachavailable Ethernet interface in the IED. Each Ethernet interface has a defaultfactory IP address when the complete IED is delivered. This is not given when anadditional Ethernet interface is installed or an interface is replaced.
• The default IP address for the IED front port is 192.168.0.254 and thecorresponding subnetwork mask is 255.255.255.0, which can be set via theLHMI path Main menu/Configuration/Communication/TCP-IPconfiguration/Front port
• The default IP address for the IED rear port is 192.168.2.10 and thecorresponding subnetwork mask is 255.255.0.0, which can be set via theLHMI path Main menu/Configuration/Communication/TCP-IPconfiguration/LAN1
The front and rear port IP addresses cannot belong to the samesubnet or communication will fail. It is recommended to change the
1MRS756801 A Section 2Starting up
630 series 13Commissioning Manual
IP address of the front port, if the front and rear port are set to thesame subnet.
Setting up the PC or workstation for point to point access to IEDsfront portA special cable is requested to connect two physical Ethernet interfaces togetherwithout a hub, router, bridge or switch in between. The Tx and Rx signal wiresmust be crossed in the cable to connect Tx with Rx on the other side and viceversa. These cables are known as null-modem cable or cross-wired cable. Theminimum length should be about 2 m. The connector type is RJ-45, see Figure 2.

The following description is an example valid for standard PCs using MicrosoftWindows operating system. The example is taken from a Laptop with one Ethernetinterface.
Administrator rights are requested to change the PC communicationsetup. Some PCs have the feature to automatically detect that Txsignals from the IED are received on the Tx pin on the PC. Thusstraight (standard) Ethernet cable can be used.
The IEDs DHCP server for the front port assigns an IP address for the computer.The computer must be configured to obtain its IP address automatically asdescribed in the following procedure.
1. Select Network Connections in the PC, see Figure 3.

Section 2 1MRS756801 AStarting up
16 630 seriesCommissioning Manual
2.6 Writing an application configuration to the IED
Ensure that the IED includes the correct application configurationaccording to project specifications.
The application configuration is created using PCM600 and then written to theIED. Establish a connection between PCM600 and the IED when an applicationconfiguration must be written to IED.
When writing an application configuration to the IED, the IED is automatically setin configuration mode. When the IED is set in configuration mode, all functionsare blocked. The red Trip LED on the IED flashes, and the green Ready LED is litwhile the IED is in the configuration mode. When the writing procedure iscompleted, the IED is automatically set into normal mode.
Be sure to set the correct technical key in IED and PCM600 toprevent writing an application configuration to the wrong IED.
See the engineering manual for information on how to create ormodify an application configuration and how to write to IED.
Set setting parameters through the LHMI. See the operation manualfor information on how to change a setting from the LHMI.
2.7 Checking CT circuits
The CTs must be connected in accordance with the terminal diagram provided withthe IED, both with regards to phases and polarity. The following tests arerecommended for every primary CT or CT core connected to the IED.
• Primary injection test to verify the current ratio of the CT, the correct wiringup to the protection IED and correct phase sequence connection (that is L1,L2, L3.)
• Polarity check to prove that the predicted direction of secondary current flowis correct for a given direction of primary current flow. This is an essential testfor the proper operation of the directional function, protection or measurementin the IED.
• CT secondary loop resistance measurement to confirm that the currenttransformer secondary loop dc resistance is within specification and that thereare no high resistance joints in the CT winding or wiring.
1MRS756801 A Section 2Starting up
630 series 17Commissioning Manual
• CT excitation test to ensure that the correct core in the CT is connected to theIED. Normally only a few points along the excitation curve are checked toensure that there are no wiring errors in the system, for example due to amistake in connecting the CT's measurement core to the IED.
• Earthing check of the individual CT secondary circuits to verify that each three-phase set of main CTs is properly connected to the station earth and only atone electrical point.
• Insulation resistance check.
Both primary and secondary sides must be disconnected from theline and IED when plotting the excitation characteristics.
2.8 Checking VT circuits
Check that the wiring is in strict accordance with the supplied connection diagram.
Do not continue before any errors are corrected.
Test the circuitry.
• Polarity check• VT circuit voltage measurement (primary injection test)• Earthing check• Phase relationship• Insulation resistance check
The polarity check verifies the integrity of circuits and the phase relationships. Thepolarity should be measured as close to the IED as possible to ensure that most ofthe wiring is also checked.
The primary injection test verifies the VT ratio and the wiring all the way throughfrom the primary system to the IED. Injection must be performed for each phase-to-neutral circuit and each phase-to-phase pair. In each case voltages in all phases andneutral are measured.
2.9 Checking the RTXP test switch
The RTXP test switch is designed to provide the means of safe testing of the IED.This is achieved by the electromechanical design of the test switch and test plughandle, when the test plug handle is inserted it first blocks the trip and alarm
Section 2 1MRS756801 AStarting up
18 630 seriesCommissioning Manual
circuits then it short circuit CT secondary circuit and opens VT secondary circuitsmaking the IED available for secondary injection.
When pulled out the test handle is mechanically stopped in half withdrawnposition, in this position the current and voltage enter the protection, but the alarmand trip circuits are still isolated.
Not until the test handle is completely removed the trip and alarm circuits arerestored for operation.
Verify by pulling in all cables that the contact sockets have beencrimped correctly and that they are fully inserted. This should neverbe done with current circuits in service.
Current circuit
1. Verify that the contact are of current circuit type.2. Verify that the short circuit jumpers are located in the correct slots.
Voltage circuit
1. Verify that the contact are of voltage circuit type.2. Check that no short circuit jumpers are located in the slots dedicated for voltage.
Trip and alarm circuits
1. Check that the correct type of contacts are used.
2.10 Checking transducer circuits
Verify from the manufacturer that the total circuit resistance is under specifiedvalues from the instrument (transducer) manufacturer.
2.11 Checking binary input and output circuits
2.11.1 Binary input circuitsPreferably, disconnect the binary input connector from the binary input cards.Check all connected signals so that both input level and polarity are in accordancewith the IEDs specifications.

Section 3 Establishing connection and verifying theIEC 61850 station communication
3.1 Setting the station communication
To enable IEC 61850 station communication:
• The IEC 61850-8-1 station communication functionality must be on in theLHMI. Navigate to Main menu/Configuration/Communication/IEC61850-8-1/General and set parameter Operation to On.
• To enable GOOSE communication the Operation parameter for thecorresponding GOOSE function blocks (GOOSEBINRCV andGOOSEINTLKRCV) must be set to On in the application configuration.
3.2 Verifying the communication
Connect your PC to the nearby switch and ping the connected IED and theSubstation Master PC to verify that the communication is working (up to thetransport layer). If it is possible to see all of them, then they can see each other.
The best way to verify the communication up to the application layer is to
• use a protocol analyzer, for example an Ethereal that is connected to thesubstation bus, and
• monitor the communication

Section 4 Testing IED operation
4.1 Preparing the IED to verify settings
If a test switch is included, start preparation by making the necessary connectionsto the test switch. This means connecting the test equipment according to a specificand designated IED terminal diagram.
Put the IED into test mode to facilitate the test of individual functions and preventunwanted operation caused by other functions. The test switch should then beconnected to the IED.
Verify that analog input signals from the Technical reference manual module aremeasured and recorded correctly by injecting currents and voltages required by thespecific IED.
To make testing even more effective PCM600 should be used. PCM600 includesthe Signal monitoring tool, which is useful to read of the individual currents andvoltages, their amplitudes and phase angles. In addition PCM600 contains theDisturbance handling tool. The content of reports generated by the Disturbancehandling tool can be configured which makes the work more efficient. Forexample, the tool may be configured to only show time tagged events and toexclude analog information and so on.
The disturbance report settings must be checked to ensure that indications are correct.
Functions to test, signal and parameter names can be found in the technical manual.The correct initiation of the disturbance recorder is made on start and/or release ortrip from a function. Also check that the wanted recordings of analogue (real andcalculated) and binary signals are achieved.
Parameters can be entered into different setting groups. Make sureto test functions for the same parameter setting group. If needed thetests must be repeated for all different setting groups used. Thedifference between testing the first parameter setting group and theremaining is that there is no need for testing the connections.
Observe during testing that the right method for testing must be used thatcorresponds to the actual parameters set in the activated parameter setting group.
In LHMI the directional earth fault protection low stage DPHLPDOC parametergroup 4 is active indicated by the * next to #4 and the test of the DPHLPDOC mustbe performed according to the value given for the setting Pol quantity, defaultsetting value Cross pol.
1MRS756801 A Section 4Testing IED operation
630 series 23Commissioning Manual
Set and configure the function(s) before the testing can start. Most functions arehighly flexible in that it permits a choice of functional and tripping modes. Thevarious modes are checked at the factory as part of the design verification. Incertain cases only modes with a high probability of coming into operation need tobe checked when commissioned to verify the configuration and settings.
Requirements for testing the function.
• Calculated settings• Valid configuration diagram for the IED• Valid terminal diagram for the IED• Technical manual• Three-phase test equipment
Content of the technical manual.
• Application and functionality summaries• Function blocks• Logic diagrams• Input and output signals• A list of setting parameters• Technical data for the function
The test equipment should be able to provide a three-phase supply of currents (andfor some START functions also voltage). The magnitude and angle of currents(and voltages) should be possible to vary. Check that the IED is prepared for testbefore starting the test session. Consider the logic diagram of the function whenperforming the test.
The response from a test can be viewed in different ways.
• Binary output signals• Service values in LHMI (logical signal or phasors)• A PC with PCM600 (configuration software) in debug mode
4.2 Activating test mode
The IED shall be put into test mode before testing. Test mode blocks all functionsin the IED and the individual functions to be tested can be unblocked to preventunwanted operation caused by other functions. In this way, it is possible to testslower back-up measuring functions without the interference from faster measuringfunctions. Test mode is indicated when the yellow Start LED flashes.
Procedure
Section 4 1MRS756801 ATesting IED operation
24 630 seriesCommissioning Manual
1. Browse to Main menu/Tests/IED test mode2. Set parameter TestMode to On and save the changes.
As a consequence the yellow Start LED will start flashing as a reminder andremains flashing until the test mode is switched off.
4.3 Preparing the connection to the test equipment
The IED can be equipped with a test switch of type RTXP8, RTXP18 or RTXP24.The test switch and its associated test plug handle (RTXH8, RTXH18 or RTXH24)are a part of the COMBITEST system, which provide secure and convenienttesting of the IED.
When using the COMBITEST, preparations for testing are automatically carriedout in the proper sequence, that is for example, blocking of tripping circuits, shortcircuiting of CT’s, opening of voltage circuits, making IED terminals available forsecondary injection). Terminals 1 and 8, 1 and 18 as well as 1 and 12 of the testswitches RTXP8, RTXP18 and RTXP24 respectively are not disconnected as theysupply DC power to the protection IED.
The RTXH test-plug handle leads may be connected to any type of test equipmentor instrument. When a number of protection IEDs of the same type are tested, thetest-plug handle only needs to be moved from the test switch of one protection IEDto the test switch of the other, without altering previous connections.
Use COMBITEST test system to prevent unwanted tripping when the handle iswithdrawn, since latches on the handle secure it in the half withdrawn position. Inthis position, all voltages and currents are restored and any reenergizing transientsare given a chance to decay before the trip circuits are restored. When the latchesare released, the handle can be completely withdrawn from the test switch,restoring the trip circuits to the protection IED.
If a test switch is not used, take measures according to provided circuit diagrams.
Never disconnect the secondary connection of a current transformercircuit without short-circuiting the transformer's secondarywinding. Operating a current transformer with the secondarywinding open will cause a massive potential build up that maydamage the transformer and injure humans.
4.4 Connecting test equipment to the IED
Connect the test equipment according to the IED specific connection diagram.
1MRS756801 A Section 4Testing IED operation
630 series 25Commissioning Manual
Pay attention to the current polarity. Make sure that the connection of input andoutput current terminals and the connection of the residual current conductor iscorrect. Check that the input and output logical signals in the logic diagram for thefunction under test are connected to the corresponding binary inputs and outputs ofthe IED under test.
4.5 Releasing the function to be tested
Release or unblock the function to be tested. This is done to ensure that only thefunction or the chain of functions to be tested are in operation and that otherfunctions are prevented from operating. The user can release the tested function(s)by setting the corresponding Blocked parameter under Function test modes to No inLHMI.
When testing a function in this blocking feature, remember that not only the actualfunction must be activated, but the whole sequence of interconnected functions(from measuring inputs to binary output contacts), including logic and so on.Before starting a new test mode session the user should scroll through everyfunction to ensure that only the function to be tested (and the interconnected ones)have the parameters Blocked and eventually EvDisable are set to No and Yesrespectively. Remember that a function is also blocked if the BLOCK input signalon the corresponding function block is active, which depends on the configuration.Ensure that the logical status of the BLOCK input signal is equal to 0 for thefunction to be tested. Event function blocks can also individually be blocked toensure that no events are reported to a remote station during the test. This is doneby setting the parameter EvDisable to Yes.
Any function is blocked if the corresponding setting in LHMI underMain menu/Tests/Function test modes menu remains On, that isthe parameter Blocked is set to Yes and the parameter TestModeunder the Main menu/Tests/IED test mode remains active. Allfunctions that were blocked or released from a previous test modesession, that is the parameter Test mode is set to On, are reset whena new test mode session is started.
Procedure
1. Browse to the Function test modes menu.The Function test modes menu is located in LHMI under Main menu/Tests/Function test modes.
2. Browse to the function instance that should be released.3. Set parameter Blocked for the selected function to Yes.

4.6 Verifying analog primary and secondarymeasurement
Verify that the connections are correct and that measuring and scaling is correctly.This is done by injecting current and voltage to the IED.
Apply input signals as needed according to the actual hardware andthe application configuration made in PCM600.
Procedure
1. Inject a symmetrical three-phase voltage and current at rated value.2. Compare the injected value with the measured values.
The voltage and current phasor menu in LHMI is located under Main menu/Measurements.
3. Compare the frequency reading with the set frequency and the direction of thepower.The frequency and active power are located under Main menu/Tests/Function status/Monitoring/PWRMMXU()PQf:1/Outputs. Then navigateto the bottom of the list to find the frequency.
4. Inject an unsymmetrical three phase voltage and current, to verify that phasesare correctly connected.
If some setting deviates check the analog input settings under
Main menu/Configuration/Analog inputs
Measured values such as current (phase and residual)and voltages (phase-to-earth,phase-to-phase and residual)as well as active, reactive and apparent power, powerfactor phase angles as well as positive and negative sequence currents and voltagesare available in LHMI under Main menu/Monitoring/I/O status/Monitoring.
Navigate to the measurement function that contains the quantity to be checked.

Also the Signal monitoring tool in PCM600 can be used to read measured values.In many cases it is more convenient to use PCM600 since, among many things,reports on measured values can be exported from the Signal monitoring tool toother tools (for example MS Excel) further analysis.
4.7 Testing protection functionality
Each protection function must be tested individually by secondary injection.
• Verify operating levels (trip) and timers.• Verify alarm and blocking signals.• Use the disturbance handling tool in PCM600 to evaluate that the protection
function has received the correct data and responded correctly (signaling andtiming).
• Use the event viewer tool in PCM600 to check that only expected events haveoccurred.
