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.

Robust design optimization for overhead power transmission line design [PDF]

open access: yesQuy Nhon University Journal of Science
Most practical design methods for overhead power transmission lines primarily rely on empirical formulas. This paper proposes a robust design–based two-stage optimization framework for overhead power transmission line design.

Ensuring the Continuity of Power Supply to the On-Board Auxiliary Devices of the Trolleybus through the Recuperation of Kinetic Energy

open access: yesEnergies, 2021
When a trolleybus travels through insulated sections of the overhead contact line, it experiences momentary power interruptions, which adversely affect the vehicle’s on-board auxiliary subassemblies.

Overhead Power Line Damage Detection: An Innovative Approach Using Enhanced YOLOv8

open access: yesElectronics
This paper presents an enhanced version of YOLOv8 specifically designed for detecting damage in overhead power lines. Firstly, to improve the model’s robustness, an adaptive threshold mechanism is introduced that can dynamically adjust the detection ...
