At the Radom University of Technology, research work was undertaken on the impact of current asymmetry caused by random changes in the arcs in the phases of an arc furnace on heating power.
It has been shown that the effect is generally a reduction in this power combined with an increase in unit power and energy losses [3,4]. Measurements of the Pst coefficient showed that its values in the three phases of the power supply network for arc furnaces are similar but not identical [2].
