where AVR is connected in power plant.

Answer Posted / jeyapal

AVR is actually a PID Controller operating on a set point ,receiving a feed back sample of output voltage of an alternator and comparing with set point.Maintains output voltage and power factor by regulating the excitation level.Construction looks very simple in the form of a printed circuit board located just on the alternator or at times inside switch board panel with a cable run to the generator.
