摘要
对雷击浪涌电流测量进行了理论分析及各种测量方法的对比,提出了一种基于霍尔效应原理的非接触式测量雷击浪涌电流的方法,该方法可测量高达200 kA的电流。
Lightning surge current measurement problems were studied.Through theoretical analysis and comparison of various measurement methods,a non-contact measurement method of lightning surge current based on hall effect principle was proposed,by which up to 200 kA current could be measured.
