An automatic voltage regulator (AVR) is an electronic device that maintains a generator’s output voltage at a stable, preset level. In diesel and other standby generators, the AVR continuously monitors voltage at the generator terminals and automatically adjusts the alternator’s excitation to compensate for load changes. This prevents voltage from rising too high or dropping […]
