Abstract :
This paper presents a new method for determination of instantaneous magnetization characteristics of transformers (saturation and hysteresis loop) by taking into account only the RMS values and no-load losses. This model is used to accurately study ferroresonance phenomena in a system of a cable-connected transformer
