Answer Posted / ankaraju.k
At the designing of transformer you can not predict which
type of load is placed on thatone i.e; the power factor is
unknown.under no load conditions thhe transformer losses is
depend on nearly sqare of voltage.under load condition the
losses depends on sqare of current.So overall losses in
transformer is depends on voltage and current only,so yhe
rating is inKVA
