Abstract:Arc grounding is a hidden trouble that it threaten electric power and distribution network of  safe function. The grounding scheme passing arc suppression coil or small resistance play a certain part in protection, but it exists certain vices.The paper introduces a kind of new protective method that arc suppression and overvoltage combination,dissertate its principium and characteristic,in order to find a best protective method it adapt to our country electric power and  distribution network function scheme.
