Question: The distance measurement of sheath fault in the cable fault inspection tester Answer: 1.1 The significance of cable sheath fault detection 1.2 The cause of cable sheath fault 1.3 The nature of cable sheath fault classification 1.4 The cable sheath fault detection process Loss problem: fault location of sheath in cable fault inspection tester Answer: 1.1 The significance of cable sheath fault detection 1.2 Reasons of cable sheath fault 1.3 Classification of cable sheath fault properties 1.4 Cable sheath fault detection process 1. Circulation will occur It causes loss and heat generation, which leads to local overheating of insulation and accelerates insulation aging, which seriously limits power transmission and affects the life of main insulation. Second, the main insulation produces electric field concentration where the metal sheath is corroded, which is easy to produce partial discharge and cause electrical trees, which is very harmful to the cable. short-term operational security threats. 3. The insulation damage of the cable sheath leads to the intrusion of water, and the probability of water tree aging of the main insulation increases, which has a serious impact on the life of the cable.
