High Voltage Overhead Power Line Routing under an Objective Observability Criterion [PDF]

open access: yesEnergies, 2017
The construction of new high voltage overhead power lines (HVOPLs) has become a controversial issue for electricity companies due to social opposition. Citizens are concerned about how these power lines may have an impact on their lives, basically caused

AUTONOMOUS CAPACITIVE POWER SUPPLY FOR DEVICES WHICH MEASURES THE PARAMETERS OF THE OVERHEAD POWER LINES

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2017
This article consider the main types of autonomous power sources for devices, which measures characteristics of overhead power lines. The calculations of the power of capacitive power supply depending of its length for the 110 kV line were done.

Method for control the mechanical parameters of overhead power lines based on improved inclinometry

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2019
Structural elements of overhead power transmission lines are experiencing both horizontal and vertical loads. Wires and cables are elements of the overhead power line, on which changes in mechanical loads are observed to a greater degree. This occurs due

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.

Three-Phase and Single-Phase Measurement of Overhead Power Line Impedance Evaluation

open access: yesEnergies, 2021
Calculation and measurement of the overhead power lines electrical parameters is common practice in today’s electrical engineering industry; however, there is very little data to actually compare these two approaches because measured data in such detail ...

Vibration of Bundled Conductors Following Ice Shedding [PDF]

open access: yes, 2008
The dynamic behavior of bundled conductors following ice shedding from one subconductor is examined numerically using the finite-element method. An existing model of ice shedding from a single conductor is improved by developing a model of spacers which ...

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.
