1. Set
2. Apply input signal for CB closed to relevant input or inputs CBCLDL1 (2 or 3)
3. Apply the fault condition with input signal(s) for start of CCRBRF. The value of current
should be below the set value
4. Verify that phase-selection re-trip (if selected) and back-up trip are achieved after set
times. Failure to trip is simulated by keeping the signal(s) CB closed activated.
5. Disconnect the AC and the START signal(s). Keep the CB closed signal(s).
6. Apply the fault and the start again. The value of current should be below the set value
I>BlkCont .
7. Arrange disconnection of BC closed signal(s) well before set back-up trip time
simulates a correct CB tripping.
8. Verify that back-up trip is not achieved. Re-trip can appear for example, due to selection
"Re-trip without current check".
9. Disconnect injected AC and START input signals.

Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/1:TESTMODE. If another function is tested, then set
the parameter
CCRBRF(50BF)/X:CCRBRF for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
has been tested.
7.4.5

Pole discordance protection CCRPLD

Prepare the IED for verification of settings as outlined in
settings".
Values of the logical signals for CCRPLD are available on the local HMI under Main menu/
Tests/Function status/Current/CCRPLD(52PD)/X:CCRPLD. The Signal Monitoring in PCM600
shows the same signals that are available on the local HMI.
7.4.5.1

Verifying the settings

1. When CCRPLD is set for external, set setting
Settings/IED Settings/Current/CCRPLD/1:CCRPLD to activate the logic that detects
pole discordance when external pole discordance signaling is used (input EXTPDIND) in
the application configuration.
2. Activate the input EXTPDIND on CCRPLD function block, and measure the operating time
of CCRPLD.
3. Compare the measured time with the set value
4. Reset the EXTPDIND input.
5. When CCRPLD is set for unsymmetrical current detection with CB monitoring, set setting
CurrSel under Main menu/Settings/IED Settings/Current/CCRPLD/1:CCRPLD to On .
Use the TRIP signal from the configured binary output to stop the timer.
6. Repeat point 4 and 5 using OPENCMD instead of CLOSECMD. Set all three currents to
110% of
NO TRIP signal should appear due to symmetrical condition.
7.4.5.2 Completing the test
Continue to test another function or end the testing by setting the parameter
