1. Subject the IED to healthy normal load conditions for at least two seconds.
2. Apply the fault condition and slowly decrease the measured impedance to find the
operating value of the phase-to-phase fault for zone 1 according to test point 1 in
figure 39 and table 23 . 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 23 .
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 above to find the operating value for the phase-to-earth fault L3-E
according to figure 40 and table 24 .
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 5
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).
12.4.5.2 Measuring the operating time of distance protection zones
GUID-9AEFB83B-A343-4965-BB41-59062CC0DB5F 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 39 and table 23 for zone 1. Compare the result of the
measurement with the setting
tPP.
3. Repeat steps 1 to 2 to find the operating time for the phase-to-earth fault according to
test point 10 in figure 40 and table 24 . Compare the result of the measurement with the
setting tPE.
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.
12.4.6 Phase selection, quadrilateral characteristic with settable
angle FRPSPDIS
GUID-701C863B-40C6-42D7-A0C8-ECEB084B1165 v4
Prepare the IED for verification of settings as outlined in section "Preparing for test" in this
chapter.
The phase selectors operate on the same measuring principles as the impedance measuring
zones. So it is necessary to follow the same principles as for distance protection, when
performing the secondary injection tests.
Measure operating characteristics during constant current conditions. Keep the measured
current as close as possible to the rated value of its associated input transformer, or lower.
But ensure that it is higher than 30% of the rated current.
Ensure that the maximum continuous current of an IED does not exceed four times its rated
value, if the measurement of the operating characteristics runs under constant voltage
conditions.
To verify the settings the operating points according to figures 41 and 42 should be tested.
See also tables 25 and 26 for information.
