In the furnace transformer application, the Electric Arc Furnace and Ladle Furnace Transformers are the key equipment in a steel plant. The rectifier transformer is the link between the electrical grid and the AC/DC converter. Furnace transformers are used to feed electric arc ovens, which use an electric arc to melt materials. These are special power transformer in china characterized by very high secondary currents and wide secondary voltage regulation (by on-load-tap-changer) in order to cope with the furnace needs, depending on the particular kind of cycle requested.
