ABSTRACT:
In order to assure a high arc current and a high arc power with simultaneous reduction of flicker voltages, at least two juxtaposed electrodes, each having the same distance from the vertical axis of the furnace and the same electrical potential, are connected to each phase of an electric arc furnace, which is preferably a three-phase electric arc furnace. Preferably circular electrodes are employed which are conductively connected together at least in the vicinity of the electric arc.
