by an angle equal to the set IED characteristic angle (rca-dir) when forward
directional feature is selected and the CTWYEpoint configuration parameter is set
to ToObject.
If reverse directional feature is selected or CTWYEpoint configuration parameter
is set to FromObject, 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 trip.
6. Check with low polarization voltage that the feature becomes non-directional,
blocked or with memory according to the setting.

Over/Undervoltage feature

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.

Completing the test

Continue to test another function or end the test by changing the TESTMODE setting to
Disabled. Restore connections and settings to their original values, if they were
changed for testing purposes.

Secondary system supervision

Current circuit supervision CCSSPVC (87)

Prepare the IED for verification of settings outlined in Section
verify 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 IMinOp is lower than the setting
of Pickup_Block.
