An on-line monitoring system of transmission line conductor de-icing based on GSM SMS and Zigbee was firstly designed and produced

the composition and the technical features of which were 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 running status such as the temperature of conductors and the carrying current etc.were measured by the system

by which the study on the de-icing properties and the temperature-increase properties can be made.The start

the process and the effect of the de-icing were realized controlled automatically.
