Answer Posted / pradeepan
The capacity of the transformer is in KVA because it depends
the load which is connecting to the transformer.
EXAMPLE:
Power = voltage x current x power factor
If we are connecting an equipment with power factor 1 we
will get full power(kw), suppose it is 10W
And if we are connecting the equipment with power factor
0.7, the power out put will be 7W.
So depending upon the load which we are connecting to
transformer its KW varies, so we cannot rate the transformer
in KW.
