Nonideal Transformers

NONIDEAL TRANSFORMERS

A nonideal (or actual) transformer differs from an ideal transformer in that the former has hysteresis and eddy-current (core) losses, and has resistive (i 2 R) losses in its primary and secondary windings. Furthermore, the core of a nonideal transformer is not perfectly permeable, and requires a finite mmf for its magnetization. Also, because of leakage, not all fluxes link with the primary and the secondary windings simultaneously in a nonideal transformer.
