| Abstract: | This paper focus on the induced current switching test,namely,demands,principle and test circuit.Firstly,the emergency of a new type of earthing switches with auxiliary interrupters is introduced.On the basis of this type of earthing switches during induced current switching,the circuit is calculated,simulated and analyzed.In view of the actual test performance of this new type of earthing switches,it is suggested that coordination of isolation clearance and auxiliary-interrupters clearance should be concerned during induced current switching. |
