Energy harvesting for overhead power line monitoring
International Multi-Conference on Systems, Sygnals & Devices, 2012Power transmission is becoming increasingly challenging because of the growth of electricity demands and distribution of renewable energies. Therefore, an effective monitoring of power lines is of decisive importance for network management. In this paper, we propose a solution for energy harvesting from the electrostatic stray field of the power line ...

The HEMP response of an overhead power distribution line
IEEE Transactions on Power Delivery, 1989The level of transient electrical surges in power system distribution lines plays an important role in determining the overall response of the electrical power network to a high altitude electromagnetic pulse (HEMP) produced by a nuclear explosion. A previous paper has discussed a multiconductor coupling model which permits the computation of the HEMP ...

Calculation of inductance of conductors for overhead power lines
2011 IEEE EUROCON - International Conference on Computer as a Tool, 2011Phase conductors of overhead power lines are made of wires, which contain an aluminum conductive area and an area of steel to ensure strength. The aluminum wires are wrapped helically over the area of cylindrical steel. The paper shows the calculation of total induction of conductor.

Power line robotic device for overhead line inspection and maintenance
Industrial Robot: An International Journal, 2017Purpose This paper aims to focus on the design and testing of a robotic device for power line inspection and cleaning. The focus for this design is on simplicity and compactness with a goal to create a device for linemen and other power line workers to keep in their toolbox. Design/methodology/approach The prototype uses V-grooved wheels to grip the

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.

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.

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
