Research ArticleOpen accessPhrase in the titleLightning Over-Voltages on Amman-Aqaba 400 KV LineGhassan Halasa, Ibrahim Badran, Hafez El-ZayyatAn attempt is made to evaluate the lightning over-voltage failure rate for Amman- Aqaba 400kV transmission line by studying the geographical and temporal characteristics of lightning causing the line forced outages. The line was divided into three sections based on weather and pollution conditions. It was found that the line failure rate due to lightning over-voltages is low compared to … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,632 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAnalysis of the Over-Voltages Produced by Lightning Strokes in the Power Transmission System in the Southern Region of Saudi ArabiaA. U. Al-Abdulaziz, S. M. Bashi, A. A. AlthubaitiThis study deals with the simulation of lightning strokes and their effects on power network in the southern region of Saudi Arabia. The network consists of main generating stations, substations and the power transmission lines. The transient performance of the system has been investigated using the EMTP (Electro Magnetic Transient Program). Some surges were introduced to the network as in … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,213 accessesView PDF Cite

Review ArticleOpen accessIn the abstractNikola TESLARelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Nicolae Tesla, has remained and spent most of his life, making it hard to pronounce "Teslea"), is considered to be the inventor of the alternating current and uncovered cableless power transmission. It is attributed to the transmission of energy through monophase, biphasic, polyphase alternating currents and transmission of non-wired energy by electromagnetic waves (oscillations) in the industrial alternating current frequency … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 6 Nov 2017 · 13,193 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Return-Stroke of Lightning Current, Source of Electromagnetic Fields (Study, Analysis and Modelling)Dib Djalel, Haddouche Ali, Chemam FayçalIn this study we present and analysis of the return-stroke lightning current and described their models which existing in the literature by several authors for the evaluation of radiated electromagnetic fields and modelling the coupling with electrical systems based on the calculation of induced voltages. The objective of this work is to take part in the improvement of the coordination … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,546 accessesView PDF Cite
