why transformer ratings in kva?
Answer Posted / saeid
Generally speaking Watt is unite of work in physics.
Anything that does some work, on of its specification is
KW . So KW is used for whatever equipment or machine that
does work. Generator, motor, heater or a lump do work and
they are identifying by KW. However, a transformer doesn't
do any work. It only transfers electrical energy. It’s not
considered a source of power or a load for power system. As
a result, we use KVA to identify capacity of a transformer
instead of KW.
Additionally, I do not believe that this discussion is
related to power factor, copper loss or core loss of the
transformer.
