Device and method for detecting and locating defects in underground cables

摘要

A device (38) and method (210) for detecting and locating defects in a cable are provided. The device (38) and method (210) may include using sensor (36, 38) feedback to determine that an insulation defect exists and to calculate (238) the location of the insulation defect in a cable (20). The method (210) may include performing principle component analysis to determine whether an insulation defect occurs and using extracted data to determine the location of the insulation defect.
