Lightning strike protection performance research of early streamer emission terminal based on contrastive discharge test

Abstract

ESE is a new type of lightning protection device which is claimed to have an excellent lightning protection performance by injecting current to generate a lightning leader. In this paper a comparative method is applied to test ESE lightning protection performance. Rod-Rod discharge electrodes are used to simulated lightning discharge and attachment. The upper rod is worked as downward lightning leader while the bottom rod act as traditional lightning rod and ESE, they symmetrically are placed on both sides of the upper rod with purpose of verifying the lightning protection performance. 125 ± 25 μs wavefront impulse wave and various lightning discharge gap less than 3m are employed for the test. ESE is not capable to be stroked more times than traditional lightning rod during the test, which means ESE' lightning protection performance is not good as it claimed since its lightning protection scope and lightning-stroked probability are similar to the traditional lightning rod.
