As we know that the rating of the transformer remains same as we consider it from the HT or LT side. The o/p can be determined by multiplying the rating with the power factor (i.e. 0.8 which is a standard value).

KW o/p = KVA * p.f.
= 25*0.8 KW
= 20 KW

Is there any rule to select the voltage of motor based on KW rating? What is the rating above which lt motor becomes the HT motor?.
