Hi! pls i need some help re AVR of generator. I have 1 unit of gen set rated 140kw, 400volts , 50 hz.I dont know what is the reason why the AVR always damaged. I already changed 2 times but now again damaged, i noticed that the voltage has increased. I adjusted the trimmer to 400 volts during start-up. Any thoughts what could be caused by this.
thanks in advance.
thanks in advance.






RE: AVR
Also check the AVR voltage rating and the source voltage for the AVR power and sense (sometimes the same terminals).
Many AVRs have a MINIMUM allowable connected resistance. This value will be in the spec sheet. Check the exciter field resistance as well as checking for grounds.
