A Monitoring System Design in Transmission Lines based on Wireless Sensor Networks

A smart grid application in monitoring the condition of transmission line with wireless sensor networks was described in this paper. ZigBee and GPRS (General Packet Radio Service) technology were adopted in this system to ensure normal transmission of signals, even in remote areas where there is no telecommunication service, and data could be transmitted over a long distance. In addition, the system provided warnings before the damage caused by meteorological disasters to ensure the line security.
