Vibration Measurement and Data Analysis on Transformer Site

As the core equipment of the power system, the safe and stable operation of the transformer is the premise to ensure the stability of the entire power grid. It is of great significance to measure the vibration acceleration of the transformer on site and analyze the measurement data. In this paper, a scheme for measuring the vibration acceleration of transformers on site is given, and the time-displacement curve of the transformer is solved by the method of discrete Fourier transform plus frequency band filtering and the direct integration method. A large amount of data was measured in a 500kV power station, and the measured data were processed accordingly to obtain the analysis results.
