An On-line Monitoring System of Transmission Line Conductor De-icing

An on-line monitoring system of transmission line conductor de-icing based on GSM SMS and Zigbee is firstly designed and produced, the composition and the technical features of which are described. The meteorology such as the temperature, the humidity, the wind speed, the rain and snow, and the air pressure etc., the icing status of transmission lines such as the gravity of iced conductors, the deflection angel of insulators, the deviation angel of insulators for wind, gallop frequency of conductors etc., and the temperature of running conductors are measured by the system, by which the study on the de-icing properties and the temperature rising properties can be made. The beginning, the process and the effect of de-icing can be controlled automatically.
