Modeling of water tree degradation in underground polymeric power cable using time domain reflectometry method

Cross-linked polyethylene (XLPE) is a one of the insulation materials in polymeric power cable. They are usually used in underground medium voltage cables. These cables are exposed to a significant risk of premature ageing and failure of polymeric cable. One of that phenomenons is water treeing. In...
