RESUMO
This thesis presents the main electromechanical phenomena, occuring during the operating of an arc furnace, focusing the electric and magnetic ones. It also presents a digital simulation aiming to verify that the utilization of a series limiting current reactor included into the furnace feeding circuit, for arc stabilization purposes, does not reduce its operational capacity at 60 Hz. It is also presented the results of an analogic simulation, which shows that the reactor impedance seen by the furnace circuit is small at 60 Hz and relatively large at other frequencies. Hence, an effective damping of the current and voltage variations, caused by the furnace operation, can be achieved.
