A gas-insulated switching apparatus has a gas-filled housing part (3a, 3b, 4, 5) which is connected to another gas-filled part via a gas line (50, 60, 70) into which a gas manometer (52, 62, 72) or a switch that responds to pressure is connected. The gas manometer (52, 62, 72) or the switch that responds to pressure indicates the occurrence of an (internal) defect and the point where this defect occurred. <IMAGE>
