Special Aspects of Power Transfer between Electric Arc Furnace Phases

The simulation results of the electrical operating modes of the DSP-100I7 electric arc furnace with different designs of the secondary current lead—triangulated and coplanar versions with a conductive conduit—are presented. The dependences of the skewness of arc discharge power in these furnaces under symmetrical and asymmetrical current modes are obtained. The significant influence of the asymmetrical mode on the arc power skewness in these furnaces is shown.
