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.

Hi,I am working in abroad for more than 3 years in a company operating with 11kv and 6.4 MW power. I need c licence in India,can I? some other says only i can get if i work for 2 years in india only! anybody kindly clarify by doubt.Thanks
wat will be the pressure maintained inside the transformer?
Why do we perform an open-circuit test and short-circuit test on the transformer?
why excitor coil of an alternator can fail
Different STANDARDS (BS, IS, IEC etc) gives different informations on CT specification. How they correspons w r t each other (i.e I mean to say BS provides "knee point voltage" but IS does not, then how can i select CT)
how to select electrical equipment such as fuse,dg,transformer,motor,msb,wire,cable as per the connecting load..please mention any books to design,take licence
