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 input signal 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
t2 . It 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”.
9.4.7.8 Completing the test
M12104-72 v5
Continue to test another function or end the test by changing the TESTMODE
setting to Off . Restore connections and settings to their original values, if they were
changed for testing purposes.
9.4.8 Pole discordance protection CCPDSC
SEMOD55625-59 v6
Prepare the IED for verification of settings outlined in Section "Preparing the IED
to verify settings" .
9.4.8.1 Verifying the settings
SEMOD55625-63 v8
1. External detection logic, Contact function selection = ContSel setting equals
CCPDSC signal from CB. Activate the EXTPDIND binary input, and
measure the operating time of CCPDSC.
Use the TRIP signal from the configured binary output to stop the timer.
2. Compare the measured time with the set value tTrip .
3. Reset the EXTPDIND input.
4. Activate the BLKDBYAR binary input.
This test should be performed together with Autorecloser SMBRREC.
5. Activate the EXTPDIND binary input.
No TRIP signal should appear.
6. Reset both BLKDBYAR and EXTPDIND binary inputs.
7. Activate the BLOCK binary input.
8. Activate EXTPDIND binary input.
NO TRIP signal should appear.
9. Reset both BLOCK and EXTPDIND binary inputs.
10. If Internal detection logic Contact function selection = ContSel setting equals
Pole position from auxiliary contacts. Then set inputs
POLE1OPN...POLE3CL in a status that activates the pole discordance logic
and repeats step 2 to step
6 .
