Abstract :
Modern high-power DC electric arc furnaces (DC EAF) are considerable sources of power quality impacts in the electric supply systems. These impacts result from the feeding converters, but particularly also from the electric arc in the DC circuit. For an exact analysis of the DC EAF influence on the electric network, both the converter and the electric arc have to be mathematically modelled. The paper presents the results of onsite measurements at a real high-power DC EAF as well as, based on it, a new mathematical approach of the electrical EAF behaviour
