Answer Posted / imran qureshi
Rating of any electric equipment gives information about
the maximum limit of parameters upto which the losses are
considerable and not affect its operation.
In a transformer, the effecting parameters
are voltage and current only and not frequency.Because
operating frequency in a transformer is constant.
Core loss is due to the voltage and copper
loss is due to current.
KVA=1000*voltage*current
while, KW =1000*voltage*curret*power factor
(power factor depends on frequency)
