Arc Furnace Reactors are connected in series with the primary winding of arc furnace transformers to stabilize the electric arc and limit current fluctuations and voltage drops during furnace operation. By improving arc stability, these reactors enhance melting efficiency, reduce electrical stress on the power system, and protect transformers and switching equipment. Hilkar Arc Furnace Reactors are manufactured as air core or iron core designs with custom tap configurations to meet specific furnace operating requirements.
