Transformers for use in industrial applications must be designed to withstand severe and extreme operating and environmental conditions. Huge currents need to be supplied to arc and smelting furnaces for aluminum, zinc, and chlorine processing. They must operate through cyclic loads, high thermal stress, and over voltage and current conditions caused by short circuits in the furnace.
