On lightning protection and grounding of high-rises
Wang Gong-sheng · Guangdong Electric Power · 2005
High-rises have strict requirements on lightning protection;under the influence of various factors,however,they are often harmed because of irrationally installed lightning protection system.Therefore,this paper presents the design principle for lightning protection and grounding of high-rises as well as the points for attention in light-current system grounding of high-rises.Through case analysis,it expatiates on the lightning and overvoltage protection of high-rise mains system,lightning protection and specific measures of power distribution system and UPS system,lightning and overvoltage protection of communication and network system,lightning protection of terminal unit mains,protection of grounding system devices,etc.Finally,it is stressed that the design for lightning protection of high-rises should meet relevant national standards to achieve better results.
