EXPERIMENT OF ARTIFICIALLY TRIGGERED LIGHTNING TO LIGHTNING ROD AND SEMICONDUCTOR LIGHTNING ELIMINATOR

摘要

In the summer of 1998 and 1999, the experiments of triggered lightning aimed at testing and comparing the function of conventional type of lightning rod and so-called Semiconductor Lightning Eliminator (SLE) were conducted in Guangzhou. southern China. The results clearly showed the attachment process between lightning rod and downward leader. The parallel discharges between two or three SLE rods were observed. When the SLE rods were struck by triggered lightning, the flashover occurred and the lightning current measured on the bottom of lightning channel was more than 6kA for one case. The lightning current-limiting function of SLE was not observed.
