An AC arc furnace is an unbalanced, nonlinear and time varying load, which can cause many problems to the power system quality. Different studies on arc furnaces harmonics analysis can be found in the bibliography of the topic nevertheless it is very difficult obtain an exact model that take into account all the parameters that have influence in the process then for this reason it is necessary to take measurements in different conditions. In this paper we’ll present the harmonics distortions, flicker and unbalance results and conclusions about three different measurement campaigns on a iron and steel industry (SNL) with an AC arc furnace of 83 MW (170 TM) with a transformer of 120 MVA connected by a dirty line of 220 kV (55 km) with the Carregado Substation where there are another nets connected with industrial and domestic consumers.
