【Abstract】 The mechanism of secondary arc extinction by high speed grounding switches (HSGS) is analyzed.The magnitude of the secondary arc current in arc path and that of recovery voltage is differectly reduced by HSGS,that in turn reduces the extinction time of the secondary arc and assures successful single pole autoreclosure. The approach is also verified by the transient network analyzer(TNA) test and the calculation of electro magnetic transient program(EMTP).更多还原
