Abstract

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
