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

.

Refer to the alternator operating and maintenance instruc-
tions for more details.
