Abstract: This study addresses the occurrence and rectification of sheath faults in EHV XLPE cables; Primarily focusing on external interference leading to cable outer jacket damage. Various corrective actions are explored based on fault location, with detailed processes outlined for rectifying sheath faults over power cables, including fault isolation and layer reinstatement. While not imposing a direct threat to the functionality of the power cable; sheath faults can directly affect the cables current carrying capacity and can lead to the deterioration of subsequent cable layers in case it was not rectified. This comprehensive examination highlights the importance of fault identification and rectification for ensuring the reliability of EHV XLPE Cables in power transmission systems.
