Abstract:

The paper aims to investigate the most optimal remote sensing method for overhead power transmission line monitoring in Latvian conditions. Today, in various sectors of the national economy, infrastructure monitoring is important in the overall management of the system. It also plays an essential role in electric power, especially in maintaining overhead power transmission lines. Realizing the possibilities of digital development, the monitoring of power lines is more often performed by applying different remote sensing methods. The study examined and compared several remote sensing methods used for power line monitoring, however, image acquisition, creating an orthophoto map, and laser scanning from an unmanned aircraft were recognized as more optimal in Latvian conditions. The main conclusion is that for the application of remote sensing methods for overhead power line monitoring, it is necessary to find out the initial data about the power line. This study included Power Line A-24 which is mainly made up of I-type wooden supports. Also, deforestation of the protective strip of the A-24 power line is required in several places, by removing the entire tree and/or bush, but in some cases, only the removal of a specific branch is sufficient. Powerline A-24 is mostly made up of I-type wooden supports that have different vertical offsets.
