This paper presents a new method for determination of instantaneous saturation and hysteresis loops of transformers with a sinusoidal or nonsinusoidal voltage excitation by taking into account only the rms values and no-load losses. This model is used to study harmonic overvoltages in an industrial power system with saturated transformers and power factor correction capacitors. Influences of short-circuit power source and switching orders of transformer and capacitor on overvoltages are investigated.
