made for all impedance zones set with directionality (forward or
reverse).
13.4.3.2 Measuring the operating time of distance protection zones
GUID-70AEC42A-9BC7-445A-AE21-2CEC0C3A79DC v3
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
44 and table 21 for zone 1. Compare the result
of the measurement with the setting t1PP.
3. Repeat steps 1 to 2 to find the operating time for the phase-to-ground fault
according to test point 10 in figure 45 and table 22. Compare the result of the
measurement with the setting t1PG.
4. Repeat steps
1 to 2 to find the operating time for all other used measuring zones.
Observe that the zones that are not tested have to be blocked and the zone that is
tested has to be released.
13.4.3.3 Completing the test
GUID-7FA2EA27-B6E2-48AB-8D53-22425E322FFA v1
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.
13.4.4 Pole slip protection PSPPPAM (78)
SEMOD175096-3 v2
Prepare the IED for verification of settings as outlined in section
"Requirements" and
section "Preparing for test" in this chapter.
13.4.4.1 Verifying the settings
SEMOD175096-7 v3
It is assumed that setting of the pole slip protection function PSPPPAM (78) is done
according to impedances as seen in figure 46 and figure 47.
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.
