| Abstract: | The typical partial discharge in stator windings insulation of generators has been experimental studied by a new detecting method in this paper. According to the experimental results, the n|mV feature figures are apparently different corresponding to the different partial discharge types, and it was also proved the new detecting method can work perfectly even though there are noise from the outside of generators. The results reveal that the new detecting method is suitable for online monitoring of insulation faulty in generators, and it is possible to distinguish the partial discharge types using artificial intelligence. |
