ABB RER670 - Completing the Test; Initiating ZCVPSOF Automatically and Setting Mode to Impedance; Initiating ZCVPSOF Automatically and Setting Mode to Uilevel

During normal operating conditions, the BC input is de-energized.
3. Apply a two-phase fault condition corresponding to a fault at approximately
45% of the line or with impedance at 50% of the used zone setting and
current greater than 30% of IBase.
The ZACC input is activated.
4. Check that the TRIP output, external signals and indication are obtained. The
TRIP output will be obtained tSOTF after the BC input is activated.
10.4.1.2 Initiating ZCVPSOF automatically and setting mode to impedance
M13850-27 v8
1. Set AutoInitMode to Voltage and Mode to Impedance.
2. Deactivate the switch onto fault BC input.
3. Set the current and voltage inputs to lower than IPh< and UPh< for at least
tDuration.
4. Apply a two-phase fault condition corresponding to a fault at approximately
45% of the line or with impedance at 50% of the used zone setting and
current greater than 30% of IBase.
The ZACC input is activated.
5. Check that the correct TRIP output, external signals and indication are
obtained after 15 ms from the ZACC input activation.
10.4.1.3 Initiating ZCVPSOF automatically and setting mode to UILevel
GUID-E83E1B3D-026C-48DB-BB9B-43C6597DE5DB v5
1. Set AutoInitMode to Voltage and Mode to UILevel.
2. Deactivate the switch onto fault BC input.
3. Set the current and voltage inputs to lower than IPh< and UPh< for at least
tDuration.
4. Apply the two-phase currents in such a way that the magnitudes are greater
than IPh< and the two-phase voltages in such a way that the magnitudes are
lower than UPh< at least for the duration of the tDuration setting.
5. Check that the correct TRIP output, external signals and indication are
obtained.
The timing of the TRIP output depends on the tDuration setting and the
distance protection release of the ZACC input signal.
• If ZACC comes before the elapse of tDuration, TRIP will be activated
tDuration+15 ms after UPh and IPh changes are done.
• If tDuration elapses before the ZACC input signal activates, TRIP will
be activated 15 ms after the ZACC activation.

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.
