Answer Posted / d.ramesh classes
efficiency of transformer depends on core loss and copper loss. core loss depends mainly on voltage and copper loss depends on current passing through the winding. so basically total loss i.e. efficiency depends on voltage and current that's why we rate transformer in KVA.
