Answer Posted / pradeep kumar rawat
transformer is static device there is no any rotating part
so there is no any friction losses, only iron loss and cu
loss in transformer, iron loss depend upon the voltage and
cu loss depend upon the current, there in no any loss which
depend upon power factor,so rating of transformer only in
kva.
