WebThen, the CWTFT function of Matlab, by using the Morlet wavelet, is applied to the first two IMFs to visualize the different high frequencies in that particular section of the track. The first two IMFs were chosen for the analysis in the longitudinal and vertical directions, whereas only the first one was chosen for the vertical direction. WebContinuous wavelet transform (CWT) with fast Fourier transform (FFT) algorithm (CWTFT) is presented in this paper which utilises faulted phase voltage waveform and obtain wavelet coefficients after the circuit breaker isolate the faulty phase. Depending on the energies of the wavelet coefficients, a threshold is defined.
