Locational Sensing Equipment for Detecting Ice and Damage on Transmission Lines

The paper describes a practical method for detecting ice coating on the overhead power lines wires. The scheme of connecting the locational complex to high-voltage overhead lines, as well as the functional diagram, the appearance of the information transmission scheme of the locational complex are described. The distortions of the locational signal after passing through the high-frequency path of the overhead power line are investigated. The paper proposes to use a correlation analysis of the estimation of changes in locational signals. Examples of locational detection of ice coating on ten operating power lines are given. A test bench for the diagnosis of locational complex are developed.
