Good day.
I need some advice on generator avr settings. I inherited a 250kva genset with indicated 300a per phase and 200kw full load capacity. I noticed a very high voltage output +/-250v LN and 450v LL. When running under or without load all is well with rpm at 1500 and 50hz. This set has been in service for many years with the same connected loads though i wonder why the avr was adjusted to such a high voltage. Currently loads of between 200 and 220a per phase have been recorded so probably a stupid question: If i adjusted the avr down to more acceptable voltage levels will this increase or decrease load current? As i understand, when generating electricity - high voltage = low current and visa versa. Just need some confirmation, trying to avoid overloading.
Thank you.
