Research ArticleOpen accessEvery word in the titleSTUDY OF THE LIGHTNING IMPACT ON THE WIND-TURBINEDib Djalel, Guebla Abdallah, Labar HocineGenerally, lightning damage has mainly been to home appliances and telephones, Towers and power transmission and generation equipment mal functions and damage due to strikes on power lines. With the adoption of wind power generation equipment, however, lightning damage is also increasing in this area. Through his dimensional characteristics and the wind power system is more exposed in the nature … …Energy Research Journal, Vol. 5, Issue 1 · 16 Oct 2014 · 7,045 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Approach of Electromagnetic Fields of the Lightning DischargeDib Djalel, Mordjaoui Mourad, Hocine LabarDespite the significant developments in the protection means of electrical and electronic systems against the lightning and its effects. With its unpredictability and aggress if character, the lightning is the most dangerous phenomenon for electrical systems, which requires more interest and greater effort by researchers and designers means of protection. We present in this study a new analytic model of … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 18 Jan 2014 · 6,912 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSuperiority of Prostration as a Protection from Lightning StrikeMiah Muhammad AdelProblem statement: Because of the significant fatalities due to lightning strikes in open fields, exploration has been made to find the human body’s most comfortable posture having the lowest length, width and height and the least ground touch in any terrain indoor and outdoor for the safest shelter from lightning strikes that neutralize an enormous amount of positive and negative … …Physics International, Vol. 3, Issue 1 · 14 May 2012 · 15,423 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Magnetic Field Induced by a Lightning Strike's Indirect Effect Double Exponential Current WaveformScott L. Meredith, Susan K. Earles, Ivica N. Kostanic, Niescja E. TurnerProblem statement: Develop a new formula which describes the magnetic field induced by a lightning strike’s indirect effect double exponential current waveform. Approach: A novel approach for developing a closed-form solution for the magnetic field from the indirect effect double exponential current waveform will be presented. In the literature, models typically employ the pulse waveform to derive the corresponding electromagnetic … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 8,191 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Horizontal Electric Field Induced by a Lightning Return StrokeScott L. Meredith, Susan K. Earles, Niescja E. TurnerProblem statement: Develop a new formula which describes the horizontal electric field induced by a lightning return stroke in contact with an imperfect conductive surface. Approach: A new method for describing the horizontal electric field induced by a lightning return stroke will be presented. The method presented here had utilized an approach which purposely downplayed the physics of how image … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,416 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsage of Lightning Arrester Line to Feed Light Electrical LoadsHani Bani Odeh, Yousif El-TousIn remote areas, light loads (tens of kilowatts) are scattered and situated in the field of high voltage lines (66KV and above). These loads are very far from the main feeders/sub-stations (33KV-0.380KV). Feeding such loads in the traditional ways like provision of Diesel-Powered Stations, installation of new distribution lines from the Feeding Centers, or building new Sub-Stations are not practical … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 8,228 accessesView PDFCite
Research ArticleOpen accessEvery word 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 PDFCite
