Motor also having losses, we call KW rating. In
transformer and generator having losses but we call KVA
Rating why?
Answer Posted / ashli
in transformer core loss depends on voltage n cu loss
depends on current and power factor has no influence..
so we express in kva rating
in case of motor rotational loss, loss due to friction
windage loss etc are present. we cant express these losses
in kva
