ABSTRACT:
An electrical system preferably constructed as gas-insulated, metal-encapsulated switching system containing at least one electrical switch located in a darkened internal space is monitored by a device for detecting interfering arcs. In this arrangement, the light pulses emanating from the interfering arcs in the internal space are optically detected, conducted out and converted into electrical signals which are processed in an evaluating device. The monitoring device should be distinguished by a short response time. This is achieved by applying electrical signals, which are attributable both to interfering arcs and to regular switching arcs, to the evaluating device and by the fact that the evaluating device also contains a circuit arrangement which detects the variation with time of the electrical signals. In this circuit arangement, the electrical signals attributable to interfering arcs are distinguished from signals attributable to regular switching arcs.
