Since,Copper loss of a transformer depends on Current and
Iron loss of a transformer depends on Voltage,hence total
loss of a transformer depends on volt-ampere and there is
no phase angle between current and voltage i.e. it is
independent of load power factor,that is the reason why
tranformer ratings in KVA not imn KW.
