Wei Sun · Gaoya dianqi · 2005
Starting from the circuit theory, the RLC impulse current cir(?)it for non-linear resistances are studied. On the basis of it, the designing theory of impulse current generator for nonlinear resistances is put forward. It is testified that, when linear waveform adjustable resistance R1 equals to 0.25 0.5 times of the total changing field of nonlinear dynamic resistance, the waveform parameters of impulse current agree with the requirement of IEC and GB standards. The fact shows that the designed circuits can be used in impulse current test for arrestors, varistors and SPD.
