Principle of Automatic Voltage Regulator

Automatic Voltage Regulator (AVR):  Automatic Voltage Regulator is a device which maintains the Generator output terminal voltage. To be more accurate, AVR is a controller which always compares the Generator output terminal voltage Vt with the set reference voltage Vrefand as per the error signal i.e. (Vref – Vt) it changes the filed excitation of … Read more Principle of Automatic Voltage Regulator
