11.8.1.6 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.
11.9 Secondary system supervision
11.9.1 Current circuit supervision CCSSPVC (87)
Prepare the IED for verification of settings outlined in Section
settings".
The Current circuit supervision function CCSSPVC (87) 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
Pickup_Block .
11.9.1.1 Verifying the settings
1. Check the input circuits and the trip value of the
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 ·
11.9.1.2 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.
11.9.2 Fuse failure supervision FUFSPVC
Prepare the IED for verification of settings as outlined in section
section "Preparing for test"
The verification is divided in two main parts. The first part is common to all fuse failure
supervision options, and checks that binary inputs and outputs trip as expected according to
actual configuration. In the second part the relevant set trip values are measured.
