As an important living facility, electric power facility is of great significance to the real-time monitoring of its working current. Based on wireless sensor network technology, a wireless sensor network consisting of multiple current acquisition nodes and a master control module of integrated wireless communication technology is developed to monitor the current of distribution network. The current acquisition node using current transformer current signal acquisition node, and through the ZigBee technology will collect the results sent to the central processing unit coordinator of the unit, by the central processing unit to deal with the data after using GPRS technology sends the data to match the webmaster station server, at the same time using GSM sends the data to mobile terminals, such as mobile phone distribution network related staff. This paper designs and develops the hardware circuit and software program of the corresponding module. The test results show that the minimum measured current of the developed current monitoring system is 200 mA and the dynamic range is up to 24 dB.
