PURPOSE:To diagnose easily and frequently whether a fault point locating device locates a fault section out of a plurality of sections screened by insulation spaces when a flashover fault occurs in a gas-insulated apparatus operates properly or not. CONSTITUTION:A diagnosis light which is emitted from a short-circuiting light detection part 3A is received by an accident monitoring device 1A and the presence is judged, thus enabling whether a fault point locating device operates properly or not. For obtaining the diagnosis light, a method for obtaining a fluorescent light by emitting a counterlight diagnosis light to a fluorescent substance 35 and a method for obtaining a reflection light at a reflection part are available. With the counterlight diagnosis light, a method for transmitting the counterlight diagnosis light which is emitted from a light-emitting device 182 which is provided at an accident monitoring device 1A to a short-circuiting light detection part 3A using an optical fiber for diagnosis 23 which is provided in parallel with an optical fiber for receiving light 22A and a method for providing a penetration hole at the short-circuiting light detection light 3A and then allowing the counterlight diagnosis light to enter it are available. |
