Answer / mahadevan

The voltage feedback giving to AVR for maintaining the voltage certain(nominal) limit and current feedback giving to AVR for avoid operation above certain range of current value because OLTC operation in higher current load is risky.

Answer / gunasekaran

avr are 2 type one is voltage detection another one is load
compensation for voltage detection inout is voltage for
load compensation we have to give both voltage and current
so we r using gen avr are loadcompensation type

Answer / leelashar kashyap

First of all, we dont have any machine that give output without input. we have CT connected to thegenset o/p &secondry of the CT is connected to the AVR. the AVR sense the current o/p of Genset & give commond to the control system of excitation to control the excitation voltage & current.
