Analysis of Distribution Characteristics of Lightning Current Magnitude in Shanghai Area
Lightning current amplitude and its features are an important basis for lightning scientific research and design of lightning protection for electric transmission line.The mean amplitude distribution and cumulative probability distributions of positive and negative flash in Shanghai area and its sub-administrative regions including Chongming,Changxing,Baoshan,Pudong,the downtown,Qingpu,Minhang,Nanhui,Fengxian and Jinshan,are analyzed by using the monitoring data of lightning location system from 2001 to 2010.Based on those work,probability density functions of lightning current amplitude from 2001 to 2010 for each administrative region and Shanghai area are shown,which provide the according to design,rebuild and evaluation of differentiation technology and strategy of lightning protection for electric transmission line in Shanghai area.
