Voltage Problem 3 Phase Generator
Need to adjust voltage each time I turn selector switch to different setting.
By Tom kinczel on 7 September, 2017 - 7:07 pm

I have a 3 phase 125KW generator with a selector switch for 3 voltage settings 120/240 single phase, 120/208 3 phase, and 277/480 3 phase. Every time I switch the selector switch between voltages, I have to adjust the voltage using the adjustment on the voltage regulator. I changed the voltage regulator but have the same problem. Any idea what it could be.

Tom kinczel,

Previously, did you not have to manually adjust voltage when switching voltage outputs?

When did this problem start?

Can you provide any information about the generator and AVR (manufacturer, model number, etc.)?
