Arc Voltage Distortion as a Source of Higher Harmonics Generated by Electric Arc Furnaces

Due to high unit capacities, electric arc furnaces are among the receivers that significantly affect power system from which they supplied. Arc generate a number of disturbances grid, including fast-changing voltage fluctuations causing phenomenon flickering light, asymmetry, and deformation curve. The main issues discussed in article problems related distortion current waveforms, resulting operation furnaces. An analysis indices characterizing recorded supply network is presented. changes range waveform individual smelting phases furnace also Furthermore, degree waveforms an A multi-voltage model used computer simulations proposed.
