10.7.1.2 Completing the test
M16289-57 v5
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.
10.8 Secondary system supervision
SEMOD53556-1 v1
10.8.1 Current circuit supervision CCSSPVC
M12917-25 v8
Prepare the IED for verification of settings outlined in Section
"Preparing the IED
to verify settings".
Values of the logical signals for CCSSPVC are available on the local HMI under
Main menu/Tests/Function status/Secondary system supervision/
CurrentCircuitSupervision(87,INd/I)/CCSSPVC(87;INd/I):x, where x = 1, 2
and 3.
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.
The condition for this procedure is that the set value of IMinOp is lower than the
set value of Ip>Block.
10.8.1.1 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 and zero current for
reference current input ISIREF.
2. Check the phase current blocking function for both the phases by injecting
current, one phase at a time. The output signals (FAIL and ALARM) shall
reset with a delay of 3 second when the current exceeds set IP>Block value.
3. Inject a current 0.1 · IBase to the reference current input ISIREF.
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.
10.8.1.2 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.
