On the transmission line model for lightning return stroke representation
[1] The widely used transmission-line (TL) model of lightning return stroke in a vertical channel is most rigorously represented by a vertical phased array of current sources that produce a spherical transverse electromagnetic (TEM) wave in the case of return-stroke speed v equal to the speed of light c. If the radius of the lightning channel were equal to zero, the equivalent representation co...
متن کاملComment on ‘‘Return stroke transmission line model for stroke speed near and equal that of light’’ by R. Thottappillil,
[1] Electric fields on the ground 500 m, 5 km, and 50 km from the lightning channel base computed using the transmission line (TL) and antenna theory (AT) return-stroke models for a typical subsequent stroke current at the channel base and a return-stroke speed equal to the speed of light (v = c) are compared. The AT model gives a total electric field peak that is about 10% lower than the field...
متن کاملA Modified Transmission Line Model for Lightning Return Stroke Field Calculations
Modifications to the transmission line model developed at the High Voltage Research Institute, Tomsk, USSR, are presented and compared between each other and with the modification proposed by the ItalianSwiss research team. The modifications considered differ from each other by the height dependent attenuation factor for the return stroke current pulse intensity. All of the attenuation factors,...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
