Abstract

The focal point of this paper is to study the partial discharge on-line diagnostic measurement system in GIS from the aspect of electrical measurement assuming that there were not any measurement devices before the GIS being put to use. A length of coaxial cable was wound on a magnetic ring. Also by the use of an impedance alternator, a higher sensitivity was realized. The foil sensor and antenna sensor are the important parts of the perfect partial discharge measurement system in GIS. The sensitivities of the sensors were determined by comparing to the charge quantity measured by 50 Ω resistance. The characteristics of the partial discharge that was produced by a fixed protrusion, free particles and the surface contamination on the spacer was studied in the GIS simulation system
