What is a lightning protection system?

For the protection of structures containing flammable vapors, flammable gases, or liquids that can give off flammable vapors; masts and overhead ground wires may be utilized to create a catenary lightning protection system.See all results for this questionWhat is Overhead Ground Wire or Earth Wire? Definition power transmission lightning conductor protectionDec 28, 2016 · Definition: The overhead earth wire or ground wire is the form of lightning protection using a conductor or conductors. It is attached from support to support above the transmission line and well grounded at regular interval. The earth wire intercepts the direct lightning strikes, which would strike the phase conductors.Estimated Reading Time: 2 minsUS6108187A - Electric power transmission line with power transmission lightning conductor protectionAn electric power transmission line with protection devices against lightening overvoltages in the form of a lighting arrester with a surface discharge.Cited by: 19Publish Year: 1996Author: Georgy Viktorovich Podporkin, Alexandr Dmitrievich Sivaev

Lightning protection of overhead transmission lines using power transmission lightning conductor protection

Oct 01, 2015 · Abstract. In this paper, a new kind of overhead transmission line (OHL) lightning protection system based on external ground wires is analyzed. Instead of a standard ground wire, two ground wires placed at the top of separate external towers located at both sides of the protected line are used. This type of protection should be applied in specific circumstances for protection of short OHL sections which are highly endangered by lightning.Cited by: 11Publish Year: 2015Author: Mladen S.
