Testing functionality by secondary injection
4. Inject the measured voltages at rated values for at least set
5. Activate the CBOPEN binary input.
6. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
7. Inject the measured voltages at rated values for at least set
8. Activate the BLKU binary input.
9. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
10. Reset the BLKU binary input.
11. Inject the measured voltages at rated values for at least set
12. Activate the BLOCK binary input.
13. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
14. Reset the BLOCK binary input.
11.6.6.2 Completing the test
continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
11.6.7 Radial feeder protection PAPGAPC (27)
The Signal Monitoring tool in PCM600 shows the service values that are available on the Local HMI
as well.
11.6.7.1 Verifying the settings
Values of the logical signals for PAPGAPC (27) are available on the local HMI under: Main menu/
Tests/Function status/Voltage protection/RadialFeeder(27, V<)/PAPGAPC(27, V<):1
Test for fast fault clearing
• Connect the test set for the injection of three phase voltages and currents to the appropriate
terminals of the IED.
• Enable the fast fault clearance by setting
BLKDLFLT to TRUE and FUSEFAIL to FALSE.
• Also assume circuit breaker is in closed position, that is CBCLOSED is high, prior to fault
occurrence.
• Create a single phase fault on phase A such that phase A voltage is lower than
quadrature phase to phase voltage and set
• Activate carrier receive CR signal.
• Check that TRIP, TR_A, ARST and ARST_A are generated with the conditions described.
• Check that activated trip signals and pickup signals are blocked by enabling BLKTR and
BLKST.
• Check that all activated signals are disabled by BLOCK input.
• If required, perform creating faults on the remaining phases in the similar way.
