Cable diagnosis. In-situ tests with returned voltage diagnosis method in Romania

16th International Conference and Exhibition on Electricity Distribution (CIRED 2001), 2001
It has been established that in service aged cable insulation, the polar components are directly related to the presence of water trees in the solid dielectric. R-C combinations, which represent water trees from an equivalent circuit point of view, have different time constants depending on the progression of the water tree.
