Note that TRIP at this time is a pulse signal, duration should be according
to set
tPulse.
4. Inject the measured voltages at rated values for at least set
tRestore time.
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
tRestore time.
8. Activate the VTSU binary input.
9. Simultaneously disconnect all the three-phase voltages from the IED.
No TRIP signal should appear.
10. Reset the VTSU binary input.
11. Inject the measured voltages at rated values for at least set
tRestore time.
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.
9.4.4.2 Completing the test
SEMOD175023-47 v4
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.
9.5 Secondary system supervision
SEMOD53556-1 v1
9.5.1 Current circuit supervision CCSSPVC
M12917-25 v8
Prepare the IED for verification of settings outlined in Section "Preparing the IED to verify
settings" .
The Current circuit supervision function CCSSPVC is conveniently tested with the same three-
phase test set as used when testing the measuring functions in the IED.
The condition for this procedure is that the setting of IMinOp is lower than the setting of
Ip>Block.
9.5.1.1 Verifying the settings
M12917-31 v8
1. Check the input circuits and the operate value of the
IMinOp current level detector by
injecting current, one phase at a time.
2. Check the phase current blocking function for all three phases by injecting current, one
phase at a time. The output signals shall reset with a delay of 1 second when the current
exceeds 1.5 ·
IBase.
3. Inject a current 0.1 ·
IBase to the reference current input I5.
4. Increase slowly the current in one of the phases and check that FAIL output is obtained
when the current is above 0.9 ·
IBase.
9.5.1.2 Completing the test
M12917-43 v4
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.
