10-2 MEASURING AC OUTPUT SWlTFf; LOAj

TOACd+)@km77

With the circuit shown in Fig.lO-7.measurement 1smade of the AC output of the generator. An electric heater or an in- candescent lamp with a power factor of 1.Ois suitable as a load for the generator.

When the measured AC output of the generator is confirmed to be wnhin the voltage range specified in the table belon. over its voltage rating. the AC output is normal.

Measurement must be made under rated load and at rated speed; sometimes. load and speed adjustments are necessary-.

10-3 MEASURING	DC OUTPUT

SWITCH

DC TERMINAL

Fig. 10-8

Measurement is made of the DC output of the generator with the witch shown in the abobe circuit turned on while the generator is kept running at its rated speed. The DC output should be aithin 11 to 14V. Lvith the current regulated at 8.3A by adjusting the load connected to the generator.

NOTE:	If a battery	is connected	as a load to the generator, the DC output voltage will increase by approximately	1 to 2V.
Therefore, carefully observe the electrolyte level and do not to overcharge the battery.
IO-4	MEASURING	INSULATION	RESISTANCE

To measure insulation resistance. connect the megger tester across either one of the two output terminals of the socket and the earth terminal. When the measured insulation resistance of the generator is over lMI2. it is normal (over

1OMR at time of shipment).
(Be sure to turn on the circuit breaker when measuring
insulation resistance.)
If the insulation resistance is less than 1X19. drsassemble
the generator. and measure the respective resistancesof the
stator. rotor and control panel.	Fig. 10-9
