ABB Relion 670 Series REL670 - Initiating ZCVPSOF Automatically and Setting Mode to Impedance; Initiating ZCVPSOF Automatically and Setting Mode to Uilevel; Completing the Test; Phase Preference Logic PPLPHIZ

During normal operating conditions, the BC input is de-energized.
2. Set AutoInitMode to DLD disabled and Mode to Impedance.
3. Apply a three-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.
10.4.13.2 Initiating ZCVPSOF automatically and setting mode to impedance
1. Deactivate the switch onto fault BC input.
2. Set the current and voltage inputs to lower than IPh< and UPh< for at least one
second.
3. Set AutoInitMode to Voltage and Mode to Impedance.
4. Apply a three-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.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.
10.4.13.3 Initiating ZCVPSOF automatically and setting mode to UILevel
1. Deactivate the switch onto fault BC input.
2. Set the current and voltage inputs to lower than IPh< and UPh< for at least one
second.
3. Set AutoInitMode to Voltage and Mode to UILevel.
4. Apply the three-phase currents in such a way that the magnitudes are greater than
IPh< and the three-phase voltages in such a way that the magnitudes and 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.
10.4.13.4 Completing the test
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.
