RF transmission-line methods for in-service probing of concentric neutral wires in underground power distribution cables
2010
2010 IEEE International Symposium on Electrical Insulation
Failure of concentric neutral (CN) wires in an underground power distribution cable can drastically reduce its useful life. New on-line approaches are needed to assess the deterioration of the CNs and to prevent unscheduled service disruptions. In this paper, we present new methods for probing the integrity of CN wires in underground power distribution cables using RF-waves. The primary advantage of our techniques compared to traditional CN diagnostics is the easy of applying our methods to
