Comparison Analysis of HHT and Fourier Transformation in Network Fault

摘要

The paper presented the fundamental of HHT and Fourier transformation through elaborating the theory and simulation experiments on matlab. Giving specific signal ,the two transformations were used in application of partial discharge, voltage dip, and harmonic wave. Visualized spectrogram were obtained to compare the two transformations from each other, therefore, HHT and Fourier transformation can be respectively used in different practical project applications.
