AVR is used to generate and maintain the Voltage as per
alternator rated voltage level.Its stand Automatic Voltage
regulator.It has feedbach PT whicg give the running voltage
of the Alternator and as per set value in the AVR it
generate the error siganl.This signal correct the Exciter
Field Current to nullfy the error signal

Answer / amritpal singh sidhu

AVR:- Automatic Voltage Regulator.
Functions:-This AVR provides regulated voltage to the
exciter windig of the DG set. This AVR regulates the
voltage level as per requirement. In case the AVR has gone
faulty then to overcome the problem we can utilize the 12V
DC voltage from DG battery to take proper voltage with
normal load.
