Lightning 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...
متن کاملDesigning 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 کاملPerformance of Medium Voltage Overhead Distribution Lines Against Lightning Discharges
The lightning discharges are one of the main causes of interruptions of medium voltage overhead distribution lines, being the reason of great concern for the utility companies. Its destructive effects frequently extends to equipments and connected installations, with the possibility to cause personal injuries and material damages, beyond economic losses, due to out of income and the possibility...
متن کاملLightning Protection
Lightning causes deaths, injuries, damages, and significant costs and losses around the world. The global lightning flash rate is in the range of 40 to 100 lightning flashes per second, of which about 30 % are cloud-to-ground flashes. The development of theoretical and experimental researches is crucial for a better understanding of the physical phenomenon and for the characterization of lightn...
متن کاملLightning Discharge and Fundamentals of Lightning Protection
A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the topological shielding are presented. Bonding require...
