generator voltage
(OP)
Hi, i need some advice, we have generator rated 300 kw , 440 v 60 hz, brushless type. when we start eh generator it only gives 50 volts from the main terminal instead of 440 v, avr have changed already, rotating rectifier changed also, all meggered ok. but same result. freq is ok. any other thought? thanks a lot.





RE: generator voltage
1. Have you measured the voltage applied to the stationary exciter field?
2. Is the 50V you measured consistent line-to-line across all three phase configurations?
I'm wondering if you are not measuring residual voltage from rotor remnant magnetization and your exciter field is not actually being applied.
