| Abstract: | In the residual voltage tests of surge protection device(SPD) under 8/20 μs impulse current according to GB 18802.1—2002,the test results are often affected by the layout of the experiments.In this paper,the influences of the factors,such as the connection mode between high voltage probe and EUT(SPD),both leads of SPD,and the residual voltage signal transmission cable,on the residual voltage measurement results are analyzed through test and theoretical analysis.Consequently,the influencing factors and their influences are determined,and a method for accurately measuring residual voltage of SPD is put forward. |
