MONITORING OF OVERHEAD POWER LINES.

open access: yes, 2022
Monitoring of overhead power lines allows you to control their integrity and serviceability, to detect defects. For this, 3D reconstruction technologies, neural networks and computer vision are used - they allow you to collect a large list of design parameters, generate reports and defective statements.

Distribution of Magnetic Field in 400 kV Double-Circuit Transmission Lines

open access: yesApplied Sciences, 2020
A high-voltage AC double-circuit 400 kV overhead power transmission line runs from the city of Elk (Poland) to the city of Alytus (Lithuania). This international 400 kV power transmission line is potentially one of the strongest magnetic field-generating

A theoretical model of rain–wind–induced in-plane galloping on overhead transmission tower-lines system

open access: yesAdvances in Mechanical Engineering, 2015
Rain–wind–induced galloping phenomenon often occurs on overhead transmission tower-lines system, just as icing galloping and vortex-excited vibration; this kind of instability oscillation can cause power-line breakage or tower failure.
