Abstract

The principle of icing-thickness on-line monitoring of transmission line based on image edge detecting through wavelet transform is described

and a new method of on-line monitoring icing-thickness on transmission line is proposed.In this method

the pictures of iced transmission line and insulators taken by the camera on iron tower are processed immediately to extract the edges of transmission line and insulators

thus icing-thickness can be gained.The processing detail of the pictures in the monitoring system is discussed

and the implementation of the image edge extracting algorithm for calculating icing-thickness is described.An experiment in artificial climate chamber is conducted to verify the method

and the result shows that the proposed method performs well in accuracy and reliability

which infers the method can be used to on-line monitor icing-thickness on transmission line.
