Failure and Troubleshooting

Symptom

Cause

Counter measures

Circuit breaker trips. (1) Overloaded

(2) Short-circuit occurred at the load side.

Reduce the load
Get rid of cause of short-circuiting.

Even when operated
at a rated speed, no
voltage or too low
voltage generated.

(1) Poor tightening of terminals
(2) Frequency selection switch is not set to

meet the frequency to be operated.

(3) Broken or short-circuited circuit to

exciter field winding

(4) Faulty exciter
(5) Function circuit protector (CP) for AVR

protection

(6) Faulty AVR
(7) Broken or short-circuited winding of

generator main machine

(8) Faulty silicon rectifier (mounted on

generator main machine rotor)

(9) Faulty voltmeter
