MEGGER ALL CRANE FEEDERS FROM GEAR TO CRANE DISCONNECT at
15 kvDC. Record readings below
o Note; Megging one phase while the other 2 phases are ungrounded will meg the
whole system from the MV Breaker cubicle to the transformer. If the readings are
low, then the circuit will have to be isolated between components/phases.
o Caution: After megging it will take a long period of time for
the cables to discharge. Use Caution prior to regrounding the
system.
Megger readings in Megohms for complete system OPTIONAL: Megging individual feeds, crane MV switch must be opened:
Megger readings in Megohms for A phase Megger readings in Megohms for B phase Megger readings in Megohms for C phase
