Application of Internet of Things in Power-Line Monitoring

The Internet of Things (IoT) has been considered as the third revolution in the digital technology after the computer and the Internet, and it brings significant advantages to smart grid. Disaster prediction and prevention of power-lines is one of the most difficult problems for electricity transmission companies. Advanced sensing and communication technologies of IoT can effectively avoid or reduce the damage of natural disasters to the power-lines, and hence improve the reliability and stability of power transmission. In this paper, a three-layer architecture model of the Internet of things for smart grid (SG-IoT) is proposed. An overview of the key technologies in SG-IoT is given. An IoT based power-lines online monitoring system is presented.
