Transformer Both the losses of the transformer is
independent of the
power factor (cos phi), which means a transformer would not
make any change in the power factor, since both the losses
viz copper loss(depends on current) and iron loss(depends
on voltage) are independent of power factor, that is why a
Transformers rating is not on kW, but on KVA

because,ironloss is depends in voltage and cu_loss is
depends in current.so the transformer ratings in kva

why is a power transformer used only occasionally?it is used to step up at generating stations?and that needs to be done all day long !!!!!!!
