Simulation of a overhead power line
2012 11th International Conference on Environment and Electrical Engineering, 2012Overhead 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 ...

Loadability curves for the new Terna's “5F” high capacity overhead lines
2023 IEEE International Conference on Environment and Electrical Engineering and 2023 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2023Terna, the Italian Transmission System Operator, has recently introduced a new generation of HV and EHV lines (the so-called “5-phases” or 5F) allowing for a substantial reduction of EMF population exposure and increase of power transfer capacity, if ...

This work is devoted to the analysis of voltages produced on overhead distribution lines hit by direct lightning. We will consider arbitrary terminations at both line ends and, also, arbitrary positioning of the pole being struck. We will deal with lines

Energy harvesting for overhead power line monitoring
International Multi-Conference on Systems, Sygnals & Devices, 2012Power 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, 1989The 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 ...
