Identification and Utilisation of Ultrasonic Guided Waves for Inspection of ACSR Cables

摘要

Wave propagation characterised; L(0,1) to be used for defect detection. Experimental and theoretical dispersion curves are compared; good agreement achieved. Detection of 4.5% reduction (2.5 mm deep cut) in CSA achieved. Wavelet denoising improved SNR up to 24%.
