Abstract: Transformer equipment plays an essential role in the power system. Its healthy and stable operation is related to realizing the function of power distribution voltage conversion, and fault diagnosis technology can escort for the transformer’s regular operation. This paper summarizes the research status of transformer fault diagnosis technology at home and abroad, analyzes the development process of transformer fault diagnosis, compares the merits of different diagnosis methods, and analyzes the traditional method of extracting transformer fault data——dissolved gas extraction method and sound signal. Finally, the research focus and development trend of transformer fault diagnosis in the future are put forward to provide some reference for transformer fault diagnosis.

Key words: transformer, fault diagnosis, sound data, artificial intelligence
