Abstract
PURPOSE: To discriminate the generation directions of flashes and corona rays in vessel, by supporting conductors by means of at least one insulating supporting bodies in the vessels, by mounting exclusive photo-detecting portions near the insulators and by drawing the photo-signals of the photo-detecting portions outside the vessels.
CONSTITUTION: Photo-detecting portions 4 are installed in shapes that condensing glass bodies 21 portions are faced to approaching each specified insulating supporting bodies 3. The end surfaces of cylindrical portions 22 at the outsides of the vessels 1 of the glass bodies of the photo-detecting portions 4 are directly contacted with transmission fibers connected to devices 8. Consequently, rays in the one direction are excellently absorbed and can be detected by means of monitor devices 6. Thus, the locations where internal short-circuit at the inside is formed can be detcted by disposing a plurality of monitor devices 6 in shapes that the monitor devices are each faced to a plurality of insulators 3.
