摘要：

This paper presents two-dimensional (2D) transient finite element solutions of an 100 MVA three-phase electric arc furnace (EAF). In practice, it was observed that there were a few high-voltage arcs between upper side of high-carrying current electrodes and EAF roof. To specify the operation and performance of this EAF, a 2D time-stepping finite element method (FEM) program was developed and induced voltages between the roof and the electrodes at different load conditions were predicted. In addition, the effective value of induced voltages between the roof, electrodes, and water pipes by which the roof was being cooled was measured. The results obtained using the FEM simulations proved that in unbalanced and asymmetrical operations of this EAF, high-voltage arcing may occur.
