KVA mean Voltage x Current
and
KW mean Voltage x Current x Power factor
The only difference is power factor
Power factor depends upon load and its value varies from
0.5 to 1
As kw is depend upon the power factor , but kva does not
depends upon the power factor mean kva of any transformer
or generator does not change with power factor . SO to know
the correct power of transformer ,we use kva as it nothing
to do with load type or power factor value
