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.

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

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.

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 ...

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.

The measurement of corrosion in overhead power lines
Anti-Corrosion Manual, 1988One of the factors giving rise to failure of steel reinforced aluminium power line conductors (ACSR) is corrosion due to the loss of zinc galvanising from the steel. As the zinc coating deteriorates, so galvanic corrosion of the aluminium sets in, resulting in weakening of the conductor, overheating and eventual failure. The corrosion occurs within the

Electrothermal analysis of overhead power lines
2012 IEEE International Conference on Industrial Technology, 2012In this work a complete coupled electrothrmal analysis of overhead power lines is presented. The electromagnetic field problem is soved analytically for both the AAC and ACSR cases. The Joule losses thus computed are input to the thermal problem yielding the analytical expression of the thermal impedance.

Icing detector for overhead power transmission lines
2009 IEEE Intrumentation and Measurement Technology Conference, 2009This paper presents a capacitive measurement principle to detect the formation and accumulation of ice on an overhead power transmission line, for the use with an autonomous monitoring system. The proposed scheme can use either a linear or a circular type electrode geometry.

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 ...

Overhead power line design in market conditions
2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG), 2015This paper deals with the concept of the stochastic optimization methodology for power line designing, which allows optimizing transmission network planning. The paper presents a comparison of both methods applied for selecting the best line design alternative — the deterministic economic intervals method and the stochastic approach based method ...
