If reverse directional feature is selected or CTstarpoint configuration
parameter is set to Fr
omObject, the angle between current and polarizing
voltage shall be set equal to rca-dir+180°.
4. Overall check in principal as above (non-directional overcurrent feature)
5. Reverse the direction of the injection current and check that the protection
does not operate.
6. Check with low polarization voltage that the feature becomes non-directional,
blocked or with memory according to the setting.
11.8.1.5 Over/Undervoltage feature
SEMOD56488-83 v2
Procedure
1. Connect the test set for injection three-phase voltages to the appropriate
voltage terminals of the IED.
2. Inject voltage(s) in a way that relevant measured (according to setting
parameter VoltageInput) voltages are created from the test set.
3. Overall check in principal as above (non-directional overcurrent feature) and
correspondingly for the undervoltage feature.
11.8.1.6 Completing the test
SEMOD56488-99 v2
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.
11.9 Secondary system supervision
SEMOD53556-1 v1
11.9.1 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.
