Use a circuit above 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 the following table at the
rated amperage and rated rpm.
Before checking insulation resistance, be sure to short-
circuit the terminals of an AC receptacle using a wire to
discharge the electricity remained in the circuit.
(1) Connect the megger tester across either one of the two
output terminals of the AC receptacle and ground
terminal to measure the insulation resistance.
Measure it with the AC breaker on. An insulation
resistance of 1 M
Ω
or more is normal.
(
Original insulation resistance at the time of shipment
from the factory is 10 M
Ω
or more.
)
If it is less than 1 M
Ω
, disassemble the generator and
measure the insulation resistance of the stator, rotor
and control panel individually.
