Commissioning manual
Testing functionality by secondary injection
1. Connect the test set for injection of three-phase currents and three-phase
voltages to the appropriate current and voltage terminals of the IED.
2. Inject current(s) and voltage(s) in a way that relevant measured (according to
setting parameter CurrentInput and VoltageInput) currents and voltages are
created from the test set.
3. Set the relevant measuring quantity current to lag or lead (lag for negative
RCA angle and lead for positive RCA angle) the relevant polarizing quantity
voltage by an angle equal to the set IED characteristic angle (rca-dir) when
forward directional feature is selected and the CTstarpoint configuration
parameter is set to ToObject.
If reverse directional feature is selected or CTstarpoint 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 operate.
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 Off. Restore connections and settings to their original values, if they were
changed for testing purposes.

Secondary system supervision

Current circuit supervision CCSSPVC

Prepare the IED for verification of settings outlined in Section
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.
