Automatic switch onto fault logic ZCVPSOF

Prepare the IED for verification of settings outlined in Section
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.
