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.
