Abstract

This paper presents an intelligent on-line monitoring system based on the elastic wave for damage inspection on overhead transmission lines, the damage location on overhead transmission lines was successfully achieved by Gabor wavelet transform and power spectral density (PSD) technology. An overview of the system is presented, including a signal generation and acquisition system that is the elastic wave generation and acquisition system, a signal processing system that is the damage location on overhead transmission lines. The experiment results show that damage location on overhead transmission lines is successfully achieved.
