Harmonic overvoltages in industrial power system with capacitors and saturated transformers

This paper presents determination hysteresis loops 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 newer power factor correction capacitors. Influences of short-circuit power source and switching orders of transformer and capacitor on overvoltages are investigated.
