Design a vibration signal acquisition system of transformer based on piezoelectric acceleration sensor aiming at characteristics of vibration signals generated by transformer. Taking vibration console as test object

acquire vibration signal by this system output by console and use fast Fourier transform（ FFT） to analyze collected vibration signal. Test results shows that the system converts charge signal output by piezoelectric acceleration sensor to standard voltage signal and it can accurately and real-time capture vibration signals

which lay foundation for transformer fault on line monitoring.
