Because the insulation of electrical equipment problems led to a serious deterioration of the accident, the power industry suffered a great loss, electricity operators must also endure the inconvenience brought about by the blackout of. PD detection is to prevent deterioration caused by the insulation of electrical equipment failures more effective diagnostic methods, but the partial discharge detection equipment itself must be in the situation can be offline for testing. In this paper, the use of the principle of online and real-time detection features, molded-against-than-partial discharge of detection technology to study the different type than the flaws of molded high-voltage converter for the pressure test.
In this paper, important to understand the definition of partial discharge, and the measurement principle, apparatus, the composition, with the use of wiring, and the results of the analysis of its causes and treatment.
