Abstract With the deeply development of state maintenance mode, the transformer core operation condition can be simply and effectively judged through the analysis of live detection data of transformer core grounding current and then accordingly making the maintenance decision. However, maintenance personnel find that the wire of transformer protection equipment winding core grounding flat iron can also cause live detection data of transformer core grounding current abnormal. This paper introduces the new problem how to analyze, check and process in order to provide a certain amount of experience.
