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.

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.

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 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
