Section 11
Testing functionality by secondary injection
11.4.10.1

Measuring the operate limit of set values

1. Check that the input logical signals BLOCK and RELEASE and the output logical signal
TRIP are all logical zero.
2. Activate the input RELEASE on the STBPTOC function block
3. For a short while inject a current (fault current) in one phase to about 110% of the set
operating current, and switch the current off.
Observe to not exceed the maximum permitted overloading of the current circuits in the
IED.
4. Switch the fault current on and measure the operating time of STBPTOC.
Use the TRIP signal from the configured binary output to stop the timer. The operation
should be instantaneously.
5. Activate the input BLOCK on the STBPTOC function block.
6. Switch on the fault current (110% of the setting).
No TRIP signal should appear.
7. Switch off the fault current.
8. For a short while inject a current (fault current) in same phase to about 90% of the set
operating current, and switch the current off.
9. Switch the fault current on.
No TRIP signal should appear.
10. Switch off the fault current.
11. Reset the RELEASE binary input.
12. Switch the fault current on.
No TRIP signal should appear.
13. Switch the fault current off.

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.
11.4.11

Pole discordance protection CCPDSC

Prepare the IED for verification of settings as outlined in section
section
11.4.11.1

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.
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.
