TRANSMISSION LINES DIAGNOSTICS

The technology of power transmission lines diagnostics by remote sensing was developed by CPNT Cyprus 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

CPNT Cyprus developed a high-performance optical and electronics complex of aircraft-based equipment “Veyer”. 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.
