11.4.13 Automatic switch onto fault logic ZCVPSOF
Prepare the IED for verification of settings outlined in Section
settings".
The automatic switch onto fault logic function ZCVPSOF is checked using secondary injection
tests. ZCVPSOF is activated either by the external input BC or by the internal DLD. FUFSPVC is
done with a pre-fault condition where the phase voltages and currents are at zero. A three-phase
fault with zero impedance and a three-phase fault with an impedance corresponding to the whole
line is applied. This fault shall cause an instantaneous trip and result in a TRIP indication.
11.4.13.1 Activating ZCVPSOF externally
1. Set
2. Activate the switch onto fault BC input.
During normal operating conditions, the BC input is de-energized.
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
The ZACC input is activated.
4. Check that the TRIP output, external signals and indication are obtained.
