Lightning attachment to overhead power lines
2020Lightning is the main cause of unscheduled interruptions in overhead power lines, affecting reliability of power supply and thus, consequently, resulting in economic losses. Lightning-caused insulation flashover in overhead power lines is associated with the fast-front overvoltages across line insulation, arising due to direct lightning strokes or ...

Smart Tower of Overhead Power Lines
2019 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2019A distinctive feature of a smart electrical network is the continuous monitoring of the state of overhead power lines (OHL). An important problem is the effective location of the damage to the OHL, as well as monitoring the external impact of the environment causing accidents.

Roman engineering [overhead power line history]
Proceedings of the IEEE, 2003A modern engineer visiting Rome, as the author did recently, cannot fail to be impressed by the work of the Roman engineers of 2000 years ago. However much manual labor was available in the capital of the empire, the planning and construction of the Colosseum and the Pantheon were magnificent engineering achievements.

Drones for Inspection of Overhead Power Lines with Recharge Function
2020 23rd Euromicro Conference on Digital System Design (DSD), 2020In recent years drones have proven their ability to solve complex tasks autonomously and effectively. Drones have not been present as a ubiquitous technology for solving these tasks yet. The reason is mainly due to their limited flying time. The technology has great market potential in many areas if flight time could be increased.

Electrodynamics Simulation of Overhead Power Lines
IEEE Transactions on Power Delivery, 2012Electrical overhead power lines are important installations today. They are the main part of electric transmission and distribution systems that are vital to developed societies. A key factor for proper operation is correct clearance between conducting parts and earthed parts. These separations can be altered by the movement in the conductors caused by

Overhead power line stringing with UAV
2017 12th International Conference on Live Maintenance (ICOLIM), 2017The goal of this abstract is to explain the methods and procedures developed by CME — Construcao e Manutencao Electromecânica, SA to execute overhead LLW Stringing — with an intelligent flight done by UAV's — Unmanned Aerial Vehicles leading to significant cost benefits and improved security, in contrast to conventional systems (helicopters, industrial

Resultant reactive power of overhead lines
Proceedings of the IEE Part C: Monographs, 1956A method is demonstrated for arriving at simple formulae by which the resultant reactive power of overhead lines under any load condition can be quickly calculated, and in which the only line constant necessary to be known is the inductance. Tables of practical overhead-line inductances are given.

Electromagnetic Field Produced by Overhead Power Lines
2000In this paper the investigation of the EMF under the overhead transmission lines with different pole structure is perfomed. The computations are directed towards improving the analytical models for predicting electromagnetic fields and finding lines with reduced EMF emission, therefore with a reduced influence on human helth. A field theory approach is

Vibration damper for overhead power lines
The Journal of the Acoustical Society of America, 2006This invention relates to the design and manufacture of Stockbridge type vibration dampers for overhead power transmission lines. The invention provides a Stockbridge vibration damper comprising a pair of damping weights joined by a stranded steel cable, a clamp attached to the cable at a location intermediate the weights for attachment to an overhead ...
