Answer Posted / vidushi
The X-mer o/p is limited by heating and hence by the losses
in the X-mer. There are two kinds of losses in the X-mer:
copper losses (ohmic losses) and iron losses. ohmic losses
(I*I*R) depend upon current while core losses depend upon X-
mer voltage and are almost unaffected by X-mer P.F.. Hence
the rated o/p is expressed in VA (V*I) or in KVA and not in
KW.
