Answer Posted / vamsi kaushik
the losses in the transformer viz., core and copper losses
depend upon voltage and current respectively. as a
machine's rating is framed depending upon the heating
inturn on the losses, the transformer rating is always
specified in terms of voltage and current i.e., in terms of
kva rating.
moreover a transformer has to take any kind of load
irrespective of the power factor. it is not economical to
design a transformer to carry only one kind of load.
hence due to tje above two reasons the rating of a
transformer is given in terms of its kva rating.
