Basically any rotating machine depends up on power factor
and other rotational losses. Transformer is not a rotating
machine and transformer losses depends on only Iron losses &
Copper losses. Iron losses depends on voltage and Copper
losses depends on current. these losses not depends on power
factor. So Transformer rating measured in KVA.
