As rating unit of any equipment depend upon the factora
which influence its output,and output depend upon the
losses. so as in transformer the cupper loss depend upon
current and iroin loss depend upon the vlotage,and not on
powerfactor.
as we know kw= volt*current8power factor
and Kva= vlot*amp
so its very logical; to rate the transformer in KVA
