Answer Posted / zulfiquar wani
Generator and transformer are rated in KVA becoz at that
time we dont know the consumer power factor as we know that
the (KW= KVA X Cos Phi) as we know the power factor we have
ratings in KW and on the other hand motor has defined power
factor and the rating has been mentioned in KW for example
if we have transformer of rating 50KVA this rating of
transformer is its apparent power that is KVA if we
multiply the same withh the power factor 0.85 we will get
the real power that is KW
KW= KVA X Cos phi
KW = 50 X 0.85
KW= 42.5KW
