Abstract
A system for monitoring a power transmission line of a power grid, including a first comprehensive sensor () disposed at the intermediate position of a power transmission line between two towers including an altimeter, a first acceleration sensor, a temperature and humidity sensor and a rainfall sensor; a second comprehensive sensor () disposed at the cable connector of the power transmission line including a leakage current sensor, a tension sensor and a wind speed and direction sensor; and a second acceleration sensor () disposed at the intermediate position of the power transmission line between the cable connector of the power transmission line and the first comprehensive sensor (). A method for monitoring a power transmission line of a power grid, including a step of monitoring the sag condition, wind yaw angle, motion and position tracking, flutter conditions, breeze vibration level, fatigue life and icing situation of a power transmission line. The method and system for monitoring a power transmission line of a power grid effectively prevent and reduce incidents of the power transmission line of the power grid based on sensor multi-dimensional sensing technology combined with the advantages of wireless sensor network technology.
