<p>The invention relates to an electrical switching device having a first interrupter unit for interrupting and connecting an electrical line, in particular an air-insulated grounding switch. Furthermore, the invention relates to a method for switching an air-insulated grounding switch, wherein no arc owing to a voltage flashover is produced on the air-insulated grounding switch. The invention provides that a second interrupter unit, which is connected in parallel with the first interrupter unit, can be switched such that resultant striking of an arc during switching only takes place in the second interrupter unit.</p> |
