made for all impedance zones set with directionality (forward or
reverse).
Measuring the operating time of distance protection zones
Procedure:
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.
3.
Repeat steps
1
to
2
according to test point 10 in figure
measurement with the setting t1PG.
4.
Repeat steps
1
to
2
Observe that the zones that are not tested have to be blocked and the zone that is
tested has to be released.
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.
Pole slip protection PSPPPAM (78)
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 (78) 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.
