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-
