Recent years, electric wire and transformer of the rural power lines have been stolen occasionally, which disturbs power supply orders and causes severe loss to the state. On-line monitor system of electric transformer based on three detector technology is developed to fight against the theft phenomenon. This paper describes the system construction, technical features and application effect in brief. This system consists of monitoring unit, supervision center and the patrolling personnel. The three detector technology and wireless picture transmission technology are firstly used against theft in power system. A series of experiments prove its applicability. When there is someone approaching to steal the transformer, the monitoring unit about 2 meters hight above can make a alarm speech. At the same time, it takes the pictures in site. Then it sends messages and pictures to the supervision center through GPRS. If the electric wire is broken, the monitoring unit sends information of the broken line to the supervision center so that the center could inform the patrol person to catch up with the scene in time. With this system the transformer and wire can be protected in maximum safety.
