Answer / sathishkumar

both are used for voltage regulation but servo stabilizer
has better voltage regulation than AVR.
where as in AVR only 3 sterps for both boost and buck but
in servo there is n number of steps(more than 50)for boost
and buck.because in AVR only six relays involved for
regulation so the efficiency is 5% but in servo less than 1%

Answer / gaurav singh

Can anybody tell how
servo improve voltage
regulation.briefly?

Answer / k.prakashchandra

Both are voltage regulators where the latter uses motor and
contactors

My system is 22kv/3.3kv transformer. client is asking to use NGR, but as we have dedicated Neutral Earthing systems which has a value less than 1 Ohm. So i want solid comparision. Why i should not use NGR as my system is already protected.Can any one help me to get out of this.how should i reply on basis of some great comparision and calculations. Please help
