How Arc Furnace Transformers and Sympathetic Inrush Currents Affect Grid Voltage and Mitigation Measures？

Four Fast An electric arc furnace is a device that melts metal using the high temperature generated by an electric arc. It converts electrical energy into thermal energy through a transformer, then transfers the heat via the arc to the furnace charge, causing it to melt. When the arc furnace starts operating, the transformer load increases suddenly, leading to a drop in grid voltage. Additionally, due to the operational characteristics of the arc furnace, the load continues to rise over a period of time,
