Abstract: In nickel smelting process, the working conditions and surroundings for the transformer of electric furnace are worse than general electric power transformer. It is difficult to meet the requirements on reliability and safety by the conventional centralized control protection. With the development of microcomputer and field-bus technology, it is necessary to design a new type of protection and monitoring system for transformer of electric furnace. A microprocessor-based protection and monitoring system was described, which uses the embedded high performance microprocessor 87C196KC-20 as its most important micro-controller unit & the technology of CAN (Controller Area Network) making it a fully distributed microcomputer system not only to perform all sorts of the transformer protection and function of automatic coinciding and communicate with the monitoring host, but also to carry with it the function of protecting, measuring, and fault diagnosis for transformer of electric furnace.
