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 Ehv Substations in Iran
Extra high voltage (EHV) substations are extremely vulnerable to the hazard of lightning strokes therefore, the shielding of these substations with a highly reliable protective scheme (shield wires) is an essential undertaking. In this paper an attempt is made to clarify the design procedure for shielding EHV substations against lightning with special reference to Iran.
متن کاملSensitivity Assessment of Lightning Protection Device Aging Effect on Distribution Substation Insulation
Insufficient electrical endurance of equipment and insulation failure against overvoltage is one of the most effective reasons for failure the power line. Lightening, switching or other disruptive parameters can cause line outage or distribution substation failure. There are different devices used to improve the safety, reliability, and power quality of the system. Surge arresters are one of t...
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...
