P127: Voltage Controlled Overcurrent (51V)
The 51V function in P127 is a combination of I>> and U< functions to inhibit trip when
normal generator current is already bigger than I>> threshold:
Overcurrent function trip will be inhibited if current is bigger than I>> AND voltage
greather than U< (Generator ON => Live busbar).
Overcurrent function will trip if current is bigger than I>> AND voltage smaller than
U< (Generator OFF => dead MV busbar).
