Standardization of LEMP electric field instrument
摘要
Abstract
In order to give the actual value of lightning electromagnetic pulse（LEMP） electric field instrument testing results,this paper plans to complete electric field instrument standardization with laboratory bounded wave simulator,which is stimulated by lightning surge generator with 1.2/50 μs pulse voltage.It analyzes performances of the simulator through experiment and numerical simulation as well.Experimental results show that the simulator terminal matcher can be removed.Numerical simulation results show that the instrument shielded enclosure may disturb the electric field and make it bigger,but this can be ignored in the real situation.However,if the instrument exceeds one-third of the simulator working place in height,it will greatly affect the inner field distribution,which should be avoided in standardization.关键词
