Answer Posted / manoj kumar

actually rating of the machine (kva or kw) depends upon the
power factor since the load power factor to which
transformer is supplying power is not known , it may be
capacitive ,inductive , or resistive that is why its rating
is in kva and not in kw

Explain the different methods used in the choice of rotor slots for reduction of harmonic torques in an induction motor.
