A power transformer as the hub of power equipment plays an important role, and the vibration signals of the transformer body have rich transformer' s operation status information. This paper designed the multi-channel vi-bration signal acquisition board based on DSP and the PC software programmed by C language. This system can col-lect each part of the transformer body' s real-time vibration condition correctly;at the same time, the wavelet pack-et is used to analyze the frequency bands-energy distribution of the transformer' s vibration signal, and then the fea-tures of the transformer fault diagnosis can be calculated effectively.
