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.

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
