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 ...

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

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.

Limiting electric fields of HVDC overhead power lines
Radiation and Environmental Biophysics, 2014As a consequence of the increased use of renewable energy and the now long distances between energy generation and consumption, in Europe, electric power transfer by high-voltage (HV) direct current (DC) overhead power lines gains increasing importance. Thousands of kilometers of them are going to be built within the next years.

Sensing Overhead Power Lines for Accident Prevention
Transactions of the ASAE, 1994Accidental contacts between farm equipment and overhead power lines contribute to the poor safety record of agriculture. Contact is commonly with an auger or irrigation pipe being moved by hand or with a tall piece of equipment being towed by a vehicle.
