Use
a
circuit like the shown in Fig.8-8 for measuring AC output. A hot plate
or
lamp with a power factor
of
1.0
may be used as a load. Adjust the load and rpm. and check that the voltage range is as specified in
Table
8-2
at the rated amperage and rated rpm.

MEASURING INSULATION RESISTANCE
Use
a
"Dr. Robin"generator tester in megger tester
mode
or
use a megger tester to check the
insulation resistance. Connect a megger tester to
one of receptacle. output terminals and the ground
terminal, then measure the insulation resistance.
An insulation resistance
of
1
megohm
or
more is
normal. (The original insulation resistance at the
time of shipment from the factory
is
10
megohm
or more.)
If
it is less than
1
megohm, disassemble the
generator and measure the insulation resistance of
the stator, rotor and control panel individually.
