title = "A Novel Non-destructive Diagnosis Method for Cable Insulation Defect Based on Broadband Impedance Spectroscopy",
abstract = "Cables play an extremely important role in the transmission of electrical energy and communication signals in modern large-scale electrical systems. Early cable insulation defects often cause cable insulation breakdown, leading to permanent insulation damage. However, it is often very difficult to accurately detect these potential local defects. This paper proposes a novel non-destructive detection method for cable defect based on broadband impedance spectroscopy. Firstly, a simulation model of cable impedance spectrum is established. The correlation between impedance parameters and cable defects is well analyzed, and the influence of different defect locations on the cable impedance spectrum is studied. The effect of frequency spectrum on the accuracy of fault location is also analyzed. Finally, several cables of different lengths are simulated and the results show that this method has great spatial resolution within 0.3\% for cables from several meters to hundreds of meters. It indicates that this non-destructive default location method has great potential in field application of cable diagnosis.",
