Диагностика ЛЭП

The technology of power transmission lines diagnostics by remote sensing was developed by JSC «CST» to determine:

planned geodesic coordinates of the supports
span lengths;
angles of the line rotation
temperature anomalies (insulators, cables and other objects);
mechanical damage;
determination of the geometry of the underlying power line surface (forest cover, other vegetation);
analysis of the intersection with utilities (roads, pipelines, etc.) in order to determine and analyze the current state.

Equipment

For the work of JSC «CST», a high-performance complex of aircraft-based equipment “Veyer” was developed. The scanner_is designed to obtain an image of the underlying surface in the infrared part of the spectrum. Scanning takes place from an AN-72 aircraft from a height of 3000 meters.
