APPLICATION OF LASER SCANNING METHOD FOR OVERHEAD POWER LINE MONITORING

Abstract

Aim of the paper is to investigate the possibilities of applying the laser scanning method for overhead power transmission line monitoring in Latvia conditions. Today, in various sectors of the national economy, infrastructure monitoring takes an important place 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, the laser scanning method from an unmanned aerial vehicle was recognized as more optimal in Latvia conditions. Main conclusions are that for the application of remote sensing methods for overhead power line monitoring, it is initially necessary to find out the initial data about the power line. In the study included power line A-24 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.
