Litgrid to conduct aerial scanning of power transmission lines across Lithuania

Litgrid, Lithuania's electricity transmission system operator, is set to implement an advanced aerial scanning project to monitor its high-voltage power lines. From June 29 to mid-August, the company will utilize LiDAR 3D laser scanning and aerial photography technologies to collect detailed information about the condition of the network and its environment across the entire country.

This initiative aims to enhance the efficiency of network maintenance by identifying potential issues before they cause disruptions. Vidmantas Grušas, head of Litgrid's Transmission Network Department, explained that scanning from above with high-resolution imagery from various angles provides data unobtainable from ground inspections. This allows for precise assessments of lines, supports, and other infrastructure elements, as well as the identification of safe distances to vegetation and potential risks within protection zones.

The project will involve helicopters and unmanned aerial vehicles equipped with professional multi-sensor monitoring gear. The collected data will be used to create accurate 3D models and orthophoto maps of the electricity transmission lines and their surroundings, pinpointing weak spots in the infrastructure. This year, Litgrid plans to scan over 5,000 kilometers of transmission lines, with operations proceeding in stages from the eastern to the western parts of Lithuania during the summer.

The project allows for precise assessment of the condition of lines, supports, and other infrastructure elements, identification of safe distances to vegetation and other objects, and timely identification of potential risks in protection zones.
