test point 1 in figure 35 and table 32. Compare the result of the measurement
with the set value.
3. Repeat steps 1 to 2 to find the operating value for test points 2, 3 in table 32.
Observe that the zones that are not tested have to be blocked and the zone that
is tested has to be released.
4. Repeat steps 1 to 3 to find the operating value for the phase-to-earth fault L3-
E according to figure 36 and table 33.
Test points 8, 9, 10 and 11 are intended to test the directional
lines of impedance protection. Since directionality is a
common function for all six measuring zones, it is only
necessary to test points 8, 9, 10 and 11 once, in the forward
direction in order to test the accuracy of directionality
(directional angles). Directional functionality testing (trip
inside, no-trip outside) should always be made for all
impedance
zones set with directionality (forward or reverse).
11.4.8.2 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
35 and table 32 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-earth
fault
according to test point 10 in figure
36 and table 33. Compare the result of the
measurement with the setting t1PE.
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.
11.4.8.3 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 Off
. Restore connections and settings to their original values, if they were
changed for testing purposes.
11.4.9 Power swing detection ZMRPSB
M13888-2 v9
The aim is to verify that the settings of the Power swing detection function
ZMRPSB is according to the setting table and to verify that ZMRPSB operates as
expected.
