Icing on power transmission lines poses a serious threat to the safety and stability of power grids. Traditional manual patrols are inefficient and unable to effectively monitor ice conditions on the lines. This paper presents a novel ice-monitoring device that employs cylindrical arrays to predict and monitor icing parameters. By measuring the increase in ice weight on multiple cylindrical surfaces, environmental conditions such as wind speed, temperature, and water droplet content are determined. The device combines advanced modeling techniques to provide real-time and precise data, facilitating timely warnings and preventive actions. Experimental results have confirmed the accuracy of this method, offering a reliable solution for managing ice-related risks in power transmission systems.
