For steel making, electric arc furnace (EAF) is preferred rather than oxygen furnace method because of its lower capital cost, less energy requirement, flexibility, can be rapidly started and stopped and allowing varying production according to the demand. EAF can effectively remove the sulphur, phosphorous and other impurities and is suitable for high quality steel smelting. The modern submerged electric arc furnaces are highly efficient recycler of steel scrap. This paper discusses about the design and analysis of a submerged arc furnace transformer of rating 1MVA, 11kV/200-133-80V.
