A new method has been suggested for determining an analytical expression for the hysteresis loop of the transformers and non-linear reactors from the manufacturer's data giving the conventional RMS saturation curve and no load loss. The accuracy of the technique is verified by the experimental results. The analytical expression thus proposed also exhibits the hysteretic property of increasing the loop area with increase of frequency of operation. Furthermore the energy loss expression associated with the hysteresis loop is derived from the suggested expression.
