This paper introduces a fault diagnosis technique using mechanical vibration signals of circuit breakers. A new frequency-domain compact-support dyadic wavelet is constructed from the point of frequency domain. This wavelet has the characteristic of definite frequency-division. A method of wavelet transform to analytical signals has been presented. Using the constructed wavelet, not only the spread of signal in the frequency band corresponding to the scale is obtained, but also the signal… CONTINUE READING
