    Abstract: To ensure the stable operation of power system, there is a need to implement online monitoring for transformers running status. This paper summarized the current situation of transformers online monitoring method for vibration signal, and expounded and analyzed from three aspects including vibration generation mechanism factors, vibration signal acquisition and influencing factors, vibration signal analysis and fault diagnosis, forecasting the development trend of transformer on-line monitoring of vibration analysis, which provides the thought for further studying the vibration manipulation.
    Key words: transformer; winding and core vibration; signal analysis; fault diagnosis
