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 ...

Risk management of overhead electric power lines
2018 1st International Conference on Power, Energy and Smart Grid (ICPESG), 2018A Right-of-Way (ROW) is a piece of land over which electric power lines are stationed irrespective of AC and DC Transmission systems. Vegetation (dense forests) within the right of way poses the most serious threat to power lines structures. Atmospheric snow is also considered as one of the hazards but it has reduced threat.

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.

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

Intelligent Reflectometer for Monitoring Overhead Power Lines
2018 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2018The paper provides a functional block diagram of an reflectometer for transmission lines with automatic correction of a methodical error. The principle of operation of the device is based on the local method of determining the distance to the fault location: probing pulses are sent to the investigated line and signals received from the fault location ...

Lightning protection of overhead power distribution lines
IEEJ Transactions on Electrical and Electronic Engineering, 2007AbstractThere are two major protective methods against lightning outages on overhead distribution lines. One is by use of surge arresters and the other is by an overhead ground wire. Surge arresters have rather constant effect regardless of the type of lightning outage causes.

Computerized design of overhead transmission power lines
Proceedings of ESMO '93. IEEE 6th International Conference on Transmission and Distribution Construction and Live-Line Maintenance, 2002The conventional design of overhead transmission power lines by manual survey, mapping and design techniques, involve costly and time consuming activities. Massive documentation is accumulated during the preliminary studies of terrain, alternative routes selection, power-line hardware configuration, cost-effectiveness-performance optimization, and more.
