Three Pulse Cable Fault Detection Method Based on Wavelet Threshold Denoising

Abstract

This paper introduced the principle of three pulse method and the method’s advantages and disadvantages on cable fault detection, modeled three pulse detection method of cable fault in the Simulink environment, analyzed the Wavelet threshold denoising effect on cable fault detection accuracy under different threshold selection rules, and proposed a three pulse detection method based on the wavelet threshold de-noising.
