Abstract :
In this paper, we adopt a Gaussian enveloped linear chirp as the incident signal of the reflectometry for localizing and analyzing concentric neutrals corrosion in the underground power cable. We model the concentric neutrals corrosion as the cutting of the concentric neutrals. In order to find the concentric neutrals corrosion in the underground power cable, we use the adaptive recursive least squares filtering to extract the reflected signal which is from the concentric neutrals corrosion. We also estimate the resistive impedance of the concentric neutral corrosion. The experiments are conducted to verify the proposed method.
