why transformer rating in kva and motor rating in kw

Answer Posted / rahul khurana

In transformer there are tho typw of losses core losses and
copper losses. core losses depends upon voltage and copper
losses depend upon current. there is no windage losses in
transformer whereas in motor it occurs.
so, in conclusion there is no any factor in transformer
which relates with power factor so the rating of
transformer is in KVA instead of KW.
