FFT-based equal-integral-bandwidth feature extraction of vibration signal of OLTC

FFT-based equal-integral-bandwidth feature extraction of vibration signal of OLTC

This study aimed to propose an equal-integral-bandwidth feature extraction method based on fast Fourier transform (FFT) to solve the problem of cumbersome processing and a large amount of calculation in the common feature extraction algorithm for vibration signals of on-load tap changer (OLTC). Firs...
