why transformer ratings in kva?
Answer Posted / saranraj
Transformer Both the losses of the transformer is
independent of the
power factor (cos phi), which means a transformer would not
make any change in the power factor, since both the losses
viz copper loss(depends on current) and iron loss(depends
on voltage) are independent of power factor, that is why a
Transformers rating is not on kW, but on KVA
because,ironloss is depends in voltage and cu_loss is
depends in current.so the transformer ratings in kva
