Testing functionality by secondary injection
Secondary system supervision
Current circuit supervision CCSSPVC
Prepare the IED for verification of settings outlined in section
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.
Verifying the settings
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 current input and check that
FAIL output is obtained when the current is about 0.9 · IBase.
Completing the test
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.
Fuse failure supervision FUFSPVC
Prepare the IED for verification of settings outlined in section
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.
Checking that the binary inputs and outputs operate as expected
