摘要
从直击雷引起地电位上升和雷击电磁脉冲的角度出发,分析了半导体少长针消雷器降低接地电阻和降低雷电流幅值、陡度的作用,并就一些问题作出相应的解释。
From the viewpoint of rise caused by direct lightning ground potential 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.
