Transformers may experience various faults during operation. In order to analyze the cause of the fault or even predict it, electrical and chemical methods need to be used for monitoring to ensure the safe and stable operation of the transformer. This article analyzes the phenomenon of acetylene and excessive gas content detected in the insulation oil of a 500kV transformer in a certain power plant. It is preliminarily judged that acetylene is generated by intermittent arcing inside the transformer. The excessive gas content is caused by poor sealing and leakage, incomplete degassing and exhaust before the transformer is put into operation, and residual gas gradually entering the transformer oil after the transformer is put into operation. Based on the analyzed cause of the fault, preventive measures such as strengthening daily inspections, investigating potential hazards, and conducting mass spectrometry detection are proposed.
