Research on Fault Location and Monitoring Technology of Power Cable Outer Sheath
Firstly,the causes of cable outer sheath faults were analyzed,and then the traditional bridge method and step voltage method used for cable fault localization were described.The bridge method was used to pre locate the fault point of the 110 KV cable on the Shuhui Line,and then the step voltage method was used for accurate localization.Through on-site testing of the outer sheath of the 110 kV cable,it has been confirmed that the combination of pre-set potential drop method and accurate position crossing method can achieve good results.
