The no load current consists of two components
Reactive or magnetizing component Im
(It is in quadrature with the applied voltage V1. It produces flux in the core and does not consume any power)
Active or power component Iw, also know as working component
(It is in phase with the applied voltage V1. It supplies the iron losses and a small amount of primary copper loss)
