why core losses and copper losses does not depend on power
factor?

Answer Posted / vijay kandpal

Actualy transformer transfer electric power, therefor its
rating is in KVA, and the power factor only due to load
whose rating in KW
So here losses in transformer either by core and copper does
not affect the power factor.
