| Abstract;Here were introduced a method to orient insulation deterioration positions by displacing an antenna sensor around an apparatus objecting at partial discharge detection to detect any discharging noise emitted by it and its procedure. By carrying out a test objecting at 77 kV oil bushings, some effects such as possibility of orientation on failure points at precision of .+-.30 cm, possibility of discrimination on outer noises such as cable corona, and so on, could be obtained. |
