Simulation of a overhead power line

2012 11th International Conference on Environment and Electrical Engineering, 2012
Overhead power lines are the prevailing facilities to carry electric energy along big distances. Their proper functioning is very important for the current society due our highly electrical-dependent lifestyle. During their working, overhead power lines are under different phenomena, such as short-circuits, high-speed winds, extreme temperature ...

Energy harvesting for overhead power line monitoring

International Multi-Conference on Systems, Sygnals & Devices, 2012
Power 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, 1989
The 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, 2011
Phase 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.
