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.

Secondary system supervision

9.5.1

Current circuit supervision CCSSPVC

Prepare the IED for verification of settings outlined in Section
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
Ip>Block .
9.5.1.1

Verifying the settings

1. Check the input circuits and the operate value of the
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 ·
3. Inject a current 0.1 ·
4. Increase slowly the current in one of the phases and check that FAIL output is obtained
when the current is above 0.9 ·
9.5.1.2 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.
