This paper in order to reduce the electric disaster damage which is caused by with electric equipment of conventional markets is introduced the electric safety monitoring system which is suitable in conventional markets. Investigate the actual conditions about electrical equipment of conventional markets, electrical safety monitoring system was constructed. Electrical safety monitoring system to verify the performance of the experiment was to build a test bed. Research results will be used with the data for the reliability security of the electric safe system operation which follows in the conventional markets actual proof equipment construction which will be advanced.
