7-3 MEASURING INSULATION RESISTANCE

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 resis- tance.

An insulation resistance of 1MΩ or more is normal.

If it is less than 1MΩ, disassemble the gen- erator and measure the insulation resistance of the stator, rotor and control panel individu- ally.

●STATOR

(1)Measure the insulation resistance between BLUE (RGV12100),

GREEN (RGV13100T) lead and the core.

(2)Measure the insulation resistance between WHITE lead and the core.

(3)Measure the insulation resistance between BLACK lead and the core.

(4)Measure the insulation resistance between RED lead and the core.
