| Abstract: | The soundness of the insulating sheath is one of the important pre-requirements for the safe operation of XLPE cables above 35 kV. This paper suggests a method for on-line monitoring of the insulating sheath based on the discussion of the damage of the broken insulating sheath to the cable operation. It also makes evaluation on the fault detection methods that are prevalent nowadays. |
