Testing functionality by secondary injection
1.
Subject the IED to healthy normal load conditions for at least two seconds.
2.
Apply the fault condition to find the operating time for the phase-to-phase fault
according to test point 10 in figure
of the measurement with the setting t1PP.

Observe that the zones that are not tested have to be blocked and the zone that is
tested has to be released.
When the load shaped characteristic is activated (OperationLdCmp = On) the
test point for phase-to-phase faults is 12 in figure
earth faults according to P12 in figure
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.
Pole slip protection PSPPPAM
Prepare the IED for verification of settings as outlined in section
section
"Preparing for test"
Verifying the settings
It is assumed that setting of the pole slip protection function PSPPPAM is done
according to impedances as seen in figure
The test is done by means of injection of three-phase current and three-phase voltage
from a modern test device. This test device shall be able to give voltage and current
with the possibility to change voltage and current amplitude and the angle between the
injected voltage and current. The parameter setting shall be according to the real
application chosen values.
Procedure
1.
Feed the IED with current and voltage corresponding to a normal operation point
Injected voltage U equal to base voltage (UBase) and the injected current I equal
to half the base current (IBase). The angle between the voltage and current shall
be 0°.
2.
With maintained amplitude of the injected voltage the current amplitude and
angle is changed to a value ZC/2.
