| Abstract: | Power cables are getting more and more important in power systems. Based on the kinds of cables (OF cable or XLPE cable),diagnosis targets (main insulation or joint) and voltage levels,different kinds of diagnosis methods have been developed,among which online diagnosis methods have received a lot of attentions. However,the knowledge of these methods is very limited,and much effort should be put on the development of online diagnosis techniques of power cables. In this paper,some developed online diagnosis methods that have been employed were presented,and the development trend of online diagnosis technique were pointed out. |
| Keywords: | oil-filled(OF) cable cross-linked polyethylene(XLPE) cable main insulation joint online diagnosis technique |
