The Simulation Research on Propagation Characteristics of Acoustic Signal Generated By Buffer Layer Ablation Defects in High Voltage Cable

High voltage cables are widely used and directly associated with the reliability and safety of urban power transmission. However, nowadays, the ablation defect in high voltage cable has caused trouble to power systems. This kind of defect occurs in the buffer layer (semi-conductive water-blocking tape) of the high voltage cable and is hard to be detected using conventional techniques. Therefore, t...
