Answer Posted / harit thaker
because transformer depend on the load and we do not know the load which is either inductive or capacitive. when the load connected with transformer so the power factor always reduce so that time reactive power taking action so losses is increase but we maintain the power factor nearly 0.98 to unity at that time only getting active power when power factor reduces the reactive power taking action that time active power become low according to power triangular so that transformer rating is always in kva.
