9.6.3.2 Completing the test
M16256-39 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.
9.7 Secondary system supervision
SEMOD53556-1 v1
9.7.1 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.
9.7.1.1 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.
9.7.1.2 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.
9.7.2 Fuse failure supervision FUFSPVC
M1405-2 v8
Prepare the IED for verification of settings outlined in Section
"Preparing the IED
to verify settings".
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 operate as
expected according to actual configuration. In the second part the relevant set
operate values are measured.
