Patent ID: 10247782

Abstract:
A method and a system (9) for testing a switching installation (30) for power transmission installations are provided. The switching installation (30) comprises a switch (2) which either connects a first side (6) of the switch (2) to a second side (7) of the switch (2) or disconnects it therefrom, and comprises two earthing switches (10, 11). Each of the two earthing switches (10, 11) is provided to either connect the first side (6) or the second side (7) to earth (1) or to disconnect it from earth (1). To test the switching installation (30), a current is generated through the switch (2) and a magnitude of the current through the switch (2) is determined. In this respect, the two earthing switches (10, 11) are closed while the current is generated and while the magnitude of the current is determined.
