Abstract From the viewpoint of ground potential rise caused by direct lightning and lightning electromagnetic pulse，the effect on the reduction of the grounding resistance，amplitude and steepness of the lightning current led by the semiconductor lightning eliminator（SLE）is analyzed. The corresponding explanation on a number of issues is given.
