Answer Posted / prasad
In all A.C. machines (which includes motors whose rating
are in KW )iron losses are proportional to voltage & copper
losses are proportional to current.
The machine rating is given in terms of its output. The
transformer output is electrical energy & thus its rating
is same as energy i.e. KVA.
Same is the case with generator
