ABB Relion 670 series - Completing the Test; Function Revision History; High Speed Distance for Series Compensated Line Zones, Quadrilateral and Mho Characteristic ZMFCPDIS (21); Measuring the Operating Time of Distance Protection Zones

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).
11.4.7.4 Measuring the operating time of distance protection zones
GUID-BB93C603-F43E-40CB-8EFA-3B0F280C011D v6
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
1 to 2 to find the operating time for the phase-to-ground fault according to test point
12. Compare the result of the measurement to the setting t1PG.
4. Repeat steps
1 to 2 to find the operating time for all other used measuring zones.
The zones that are not tested have to be blocked and the zone that is tested has to be released.
11.4.7.5 Completing the test
GUID-60C5389E-B021-45BB-8CB3-E21348CF50EF v2
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
