This paper presents a study of power quality problems created by an electric arc furnace (EAF) with eccentric bottom tap (EBT) at power system. The analysis have been done to EAF of 100 t capacity used for steel melting. Experimental results show this EAF is substantial source of electric disturbances, such as voltage fluctuations, flicker, harmonics, and unbalance between phases. Improvement of the quality of electric energy at EAF imposes a careful technical and economical analysis. Of all possible solutions for improvement of the power quality for an EAF (passive filter, STATCOM or SVC), SVC is the ideal solution.
