摘要

This paper presents a study of power quality problems created by a UHP electric arc furnace (EAF) operation at power system. We are analyzing an electric arc furnace of 100 t capacity used for steel melting, and the related steel treatment installation. The measurements have been made using the CA8334 three-phase power quality analyser. Experimental results show that the EAF are a substantial source of electric disturbances, such as voltage fluctuations, flicker, harmonics, and unbalance between phases. Improvement of the energetic performances of an electric arc furnace imposes a careful technical and economical analysis, for choosing the possible solutions for balancing the load on phases, improving the wave forms (current and voltage) and improving the power factor.
