| Abstract: | The significance of condition judgement of electrical apparatus based on statistical characteristics of partial discharge (PD) extracted from PD signals detected by digital and computer-aided PD measuring device is demonstrated. It is also pointed out that the efficiency of discharge recognition is improved by using pattern recognition methods. Three pattern recognition methods based on distance: confidence intreval method,minimum distance method and centour score method are introduced. The basic principles and algorithms, samples constitutions are analysed. |
