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.

Insulator visual non-conformity detection in overhead power distribution lines using deep learning
Computers & electrical engineering, 2019Overhead Power Distribution Lines (OPDLs) correspond to a large percentage of the medium-voltage electrical systems. In these networks, visual inspection activities are usually performed without resorting to automated systems, requiring a significant ...

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 ...

IEEE Transactions on Power Systems, 2019
With regard to wind farms connected to the main system via dedicated overhead transmission lines, the available wind power absorbed by the system relies on not only the power generation capacity but also the power transmission threshold. Thus, this study

Overhead Power Line with Backup Split-Phase
2019 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon), 2019The article describes the characteristics of traditional and unconventional types of AC power transmission, such as overhead lines with a backup phase, six-phase power lines and controlled power lines FACTS. The analysis of ways to improve the efficiency and operation of overhead power lines using backup phases is 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
