Measuring the operating limit of set values

Procedure:
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 and table .
Compare the result of the measurement with the set value.
3. Repeat steps
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

9.4.1.4

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 12 for zone 1. Compare the result of the measurement to the setting tPPZ1.
3. Repeat steps
12. Compare the result of the measurement to the setting tPEZ1.

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 seven measuring zones,
it is only necessary to test 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).
