1MRK 506 371-UUS E
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 (50STB) 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 ENABLE binary input.
12. Switch the fault current on.
No TRIP signal should appear.
13. Disable the fault current.
11.5.9.2 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.
11.5.10 Pole discrepancy protection CCPDSC (52PD)
Prepare the IED for verification of settings as outlined in section
section "Preparing for test"
11.5.10.1 Verifying the settings
1. External detection logic, Contact function
(52PD) signal from CB. Activate the EXTPDIND binary input, and measure the operating time
of CCPDSC (52PD).
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 (79).
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
position from auxiliary contacts. Then set inputs 52b_A...52a_C in a status that activates the
pole discordance logic and repeats step 2 to step 6.
11. Unsymmetrical current detection with CB monitoring: Set measured current in one phase to
110% of current release level. Activate CLOSECMD and measure the operating time of the
CCPDSC (52PD) protection.
Use the TRIP signal from the configured binary output to stop the timer.
