whytransformers rating in KVA?

Answer Posted / abhishek maji

Transformers ratings are given in kVA because the operating power factor of a transformer depends on the load,it is not constant rather varies with load...Secondly if it is rated in kW then as the operating power factor is not known in advance so operating current may be more than its rated current which may affect the winding insulation due to additional heating......Thirdly a transformer acts as an interfacing device between the power generating station and the load center and as my load not only demands active power but also requires reactive power so a transformer must have the capability of handling both types of powers.. that's another reason why transformers ratings are in kVA...
