Measuring Ground Field and Corona Current of Lightning Rod During the Lightning

摘要

From measuring ground fields and corona current of lightning rod during the lightning, we can study beginning, maturing, dissipating, electrification of thunderclouds simple-body. In this paper, we report the measuring data about corona current and ground field during a lightning that was happened in Dongying, Shandong. The properties of ground fields in the course of lightning are studied. The theoretical explanation about the measuring result was provided.
