Abstract

Widespread applications of pressurized SF₆ gas and its mixtures as insulating media in many electric power apparatus are the result of recent advances in modern technologies. Partial discharge (PD) is a natural phenomenon occurring in such gas-insulated electric power systems, which invariably contains tiny defects and non-uniformities. The quality of an electrical insulation system can be characterized by PD measurements, which serve to identify the type and status of a defect. A review on the insulation and PD monitoring for gas-insulated switchgear/transmission lines (GIS/GITL) is presented with focusing on the measurement techniques. Since PD monitoring systems can generate a large amount of data, therefore computer-aided interpretation and classification of defects are also discussed.
