Cable Fault Monitoring and Indication: A Review
نویسندگان
چکیده
Underground cable power transmission and distribution system are susceptible to faults. Accurate fault location for transmission lines is of vital importance. A quick detection and analysis of faults is necessity of power retailers and distributors. This paper reviews various fault locating methods and highly computational methods proposed by research community that are currently in use. The paper also presents some guidelines for design of fault location and remote indication, for reducing power outages and reducing heavy loss of revenue.
