Actually the question itself is wrong. The rating of
Generators are also mentioned in KVA as both tr. & gen have
a same function of producing apparent power which doesn't
have power factor.

The power factor is a measurement voltage & current utilised
and it will be ratio of apparant power to active power.

But the motors are mentioned in active power as they are
used in various industrial/domestic application utilising
the current & voltage with desired power factor.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
