10.4.1.2
Activating ZCVPSOF externally
1.
Set AutoInitMode to DLD disabled and Mode to Impedance.
2.
Activate the switch onto fault BC input.
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.
10.4.1.3
Initiating ZCVPSOF automatically and setting mode to impedance
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.
10.4.1.4
Initiating ZCVPSOF automatically and setting mode to UILevel
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.
