EASURING THE ALTERNATOR INSULATION RESISTANCE
A 500-V megger is required to measure the alternator
insulation resistance.
If the N-terminal is connected to the earthing system, it must
be disconnected from the earth terminal. Disconnect the
AVR.
Connect the megger between the earth terminal and terminal
L1 and generate a voltage of 500 V. The scale must indicate
a resistance of at least 5 M
Ω
.
Refer to the alternator operating and maintenance instruc-
tions for more details.
