the taransformer is a static device which converts one form
of voltage to another form of voltage wuthout changing the
frequency,the two losses i.e,copper losses and iron losses
are depends upon current and voltage respectively.there is
no losses depending upon power factor.since the power factor
is constant,that's why the transformer ratings is on kva but
not in kw.
