transformer is nothing but power producing equipment.So the
powre p=V*I.v=Voltage,I=Amps.the minimum rating of the
distribution transformer is 1000V.i.e 1 Kilo
volt,v=volts,&I=amps.So thats while we can saying in KVA.

Moter rating in H.P & 1 H.P=0.732kiloWatts.
So moters having load is almost Drives.
