Abstract In this paper, an accident analysis process of the main transformer trip caused by the explosion of the medium voltage bushing is introduced. By means of oil chromatographic detection data, transformer disassembly inspection and other means, the type, location and cause of equipment failure are determined, and the troubleshooting, treatment and improvement methods are proposed, which providing reference for the future analysis and process.
