Review of power transformer fault diagnosis

Power transformer is the power grid of the voltage size of the place for lifting and upgrading, through the lifting and lowering of the voltage, can reduce the power loss in the transmission process and provide end users with a voltage level to meet the needs, is one of the most important equipment in the power system. Therefore, reliable condition monitoring and fast and efficient fault diagnosis of power transformers are required to ensure the good and stable operation of distribution transformers. In this paper, a comprehensive review and summary of the fault diagnosis research of power transformers is carried out.
