Answer / navaneetha

copper losses depends on current and iron losses depends on
voltage. Total transformer loss depends on volt-ampere (VA)
and not on phase angle between voltage and current i.e., it
is independent of load power factor. That is why
transformer's rating is in KVA

Answer / dinesh giri

Actully Transformer has any no its power factor.Its power
factor depends on the connected Load with it.The connected
load may be inductive or capactive or resistive Load or
mixed of all .
Connected Load rating in KW

As KVA*Power Factor(COS A)=KW

Rating of Transfarmaer is always taken in KVA

Answer / mahender mohal

Simply transformer is a power transfer device not a power
consuming device,so it have negligible loss (depends on
volt-ampere),so cos$ is >0.96 approx. 1.P=vi;due to this
reason x-mer rating is in VA Or KVA.

Answer / s. kumar

The power factor of the transformer depends on the load P.F
of the system where the transformer is connected. so the
manufacturer cant rate it in terms of KW.
