Expected result: the protection function does not issue either start or trip.

11.4.13 Automatic switch onto fault logic ZCVPSOF
M13850-2 v9
Prepare the IED for verification of settings outlined in Section
"Preparing the IED
to verify 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.
