Research on Pressure Characteristics of Tank Wall During Internal Flashover Discharge Under AC Voltage of Oil Tank

Power transformers are important equipment for power system conversion and transmission of power system. In recent years, many transformer fires and explosions have occurred in the power system, and most of them are caused by the internal arc fault of the transformer, and the internal arc has gradually developed from partial discharge. In order to have a more comprehensive understanding of the changes in the tank wall pressure during the development of the internal discharge of the transformer, and to monitor the development of the internal discharge of the transformer, this paper studies the characteristics of the tank wall pressure during flashover discharge inside the tank.
