Abstract :
This paper describes a modified algorithm for evaluating inrush current or other transients need to consider ferromagnetic characteristics of core material. In this paper the Jiles-Atherton theory with voltage source as input stimulator is used to model the transformer core including hysteresis. Applying new algorithm on a sample transformer using MATLAB, shows good results
