Fellow electricians, i would like to know if someone can clarify a doubt I have regarding AVR (Automatic Voltage Regulator) in a Chinese 220/380V diesel generator, I think of 320KVA. A collegue of mine has a problem regarding diode replacements, and i was wondering if one can fabricate something because we're unable to find the same elements in the market, only importing foreign ones. Is it possible? Or you need more information?
