Defect identification method and device applied to transformer substation, equipment and medium

The invention discloses a defect identification method, device and equipment applied to a transformer substation and a medium, and the method comprises the steps: obtaining partial discharge feature information corresponding to target power transformation equipment; processing the partial discharge characteristic information according to preset clustering information, and determining average distance information corresponding to each piece of preset clustering information; and based on the preset clustering information and the average distance information, determining a target defect type corresponding to the target power transformation equipment, and performing defect identification based on the target defect type. The target defect type corresponding to the target power transformation equipment is determined according to the partial discharge characteristic information of the target power transformation equipment, so that defect identification can be carried out based on the target defect type, and the prob
