10.5.5.8 Verifying the function mode
To be made only when
the tests in one phase only, or at three-phase trip applications for just three-phase tripping.
Checking the case with fault current above set value
The operation shall be as in
1. Set
2. Leave the inputs for CB close inactivated. These signals should not influence.
3. Apply the fault condition, including the start of CCRBRF, with the current above the set
IP> value.
4. Check that the re-trip, if selected, and back-up trip commands are achieved.
Checking the case with fault current below set value
The case shall simulate a case where the fault current is very low and operation will depend on
CB position signal from CB auxiliary contact. It is suggested that re-trip without current check
is used, setting
1. Set
2. Apply input signal for CB closed to the 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 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
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".
10.5.5.9

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.
10.5.6

Pole discordance protection CCPDSC

Prepare the IED for verification of settings as outlined in section
section
10.5.6.1

Verifying the settings

1. External detection logic, Contact function
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
3. Reset the EXTPDIND input.
4. Activate the BLKDBYAR binary input.
This test should be performed together with Autorecloser SMBRREC.
