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

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
