Designing Concept on Lightning Protection of Overhead Power Distribution Line
The principle is shown for lightning protection of power distribution lines taking the effects of surge arresters, overhead ground wires and their combined use into consideration. Moreover an outline of a rational design method targeting direct lightning hits, induced overvoltages and backflow currents from high structures.
متن کاملLightning Protection of Overhead Power Distribution Lines
Distribution lines are often located in areas with high ground flash densities, being therefore subject to lightning-caused power interruptions. This paper presents an overview of the various types of lightning overvoltages that can arise on overhead power distribution networks, as well as typical voltage waveforms. The effectivenesses of the most important methods for mitigating such overvolta...

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...
15 صفحه اولEvaluation of the Lightning Performance of an Overhead Multiconductor Transmission Line System
The lightning performance of an overhead Multiconductor Transmission Line (MTL) system is typically represented by means of curves reporting how many lightning faults per year the system may experience as a function of its insulation level [1]. In other words, it expresses the probability that the lines are subject to an overvoltage greater than their critical flashover voltage (CFO). Such curv...
متن کاملLightning-induced Overvoltages in Overhead Power Distribution Lines: Importance of the Line Grounding Electrodes Modeling
Models for the calculation of lightning-induced voltages on distribution networks, should be able to take into account the presence of shielding wires and/or neutral conductors and of their relevant groundings. The paper deals with the estimation of the influence of these groundings with particular reference to the grounding electrode model on the calculated values of the lightninginduced volta...
