Abstract
A large steel industry which has nonlinear loads including electric arc furnaces is one of the extra high voltage customers. These nonlinear loads generate harmonic currents and create distortions on the sinusoidal voltage of the power system. Harmonic field measurements have shown that the harmonic contents of a waveform varies with time. A cumulative propablistic approach is the most commonly used method to solve time varying harmonics. In this paper the in varying harmonics of electric arc furnace loads are evaluated by international harmonic standards(IEC 61000-3-6, IEEE 519 and JIS C 61000-3-2).
