Answer / shahnawaz akhter

kva meaning its rating in transformer cu loss depend on
current and iron loss depend on voltage not in phase angle
between voltage and current that's why transformer rating
in kva not kw.

Answer / sujeet

Actually, a machine's rating depends on the type of load and
since the load of a transformer can be real as well as
reactive.Hence the rating of the transformer is given in KVA
not in KW( for mechanical loads only).

Answer / bala

There is no fixed load to supply power from transformer.The
load can change at any time thats why kva used.

Answer / neeraj malik

As there are two types of losses in a t/f i.e core losses that
depends on voltage of the t/f and ohmic losses that depends on
current of the t/f.Thats why due to these losses we take the
rating of a t/f in kVA
