Electrical Arc Furnace Transformers can run on AC or DC and the power ratings can range between 20 to 200MV to stabilize the fluctuations that can be in the same tank or in a separate one. The Furnace Transformers are designed in a manner that it is completely strong and robust and can withstand the extremely high thermal stress and short-circuit conditions and are well protected also against operational over voltages, which may take place due to frequent switching. The Furnace Transformers are large capacity transformers that can be used in foundries to develop cast iron products steel smelting whereas another type of transformer called blast transformer helps in smelting of iron alloy, calcium carbide and silicide. Electrical Arc Furnace Transformers come in different designs and specification to fulfil the requirements of the furnace applications.
