Definition of Ideal Transforme r An  ideal transformer  is an imaginary transformer which does not have any loss in it, means no core losses, copper losses and any other  losses in transformer . Efficiency of this transformer is considered as 100%. Ideal Transformer Model Ideal transformer model   is developed by considering a transformer which does not have any loss. That means the windings of the transformer are purely inductive and the core of transformer is loss free. There is zero  leakage reactance of transformer . As we said, whenever we place a low reluctance core inside the windings, maximum amount of flux passes through this core, but still there is some flux which does not pass through the core but passes through the insulation used in the transformer. This flux does not take part in the transformation action of the transformer. This flux is called leakage flux of transformer . In an ideal transformer , this  "Leakage Flux in Transformer">leak
