Abstract
Ultrasonic signal will be generated when a partial discharge occurs in the oil/paper insulation system, thereby enabling partial discharge detection of the transformer. In order to explore the ultrasonic characteristics of partial discharge of oil/paper insulation system, a partial discharge detection platform based on ultrasonic method is developed in this paper. Based on the platform, the ultrasonic signal filtering method is analyzed, and the typical defect model of oil/paper insulation is built and tested in the laboratory, obtaining partial discharge signal of typical defective. Finally, the accuracy of the waveform acquired in this paper and its effectiveness in fault diagnosis are verified by the application on the actual transformer.
