The decomposition products of SF6 partial discharge (PD) were experimented to detect PD fault in the gas chamber of SF6 gas insulated ring network cabinet. The SF6 decomposition products and the decomposition characteristics of typical defects (i.e., metal protrusion and metal particle) were investigated. Two models of typical defects were constructed in the simulated gas chamber. Various discharge...
Radical frequency (RF) measurement has become hot point in field of partial discharge detection. However, a big problem that hampers the application of this method is difficult to establish a relationship between data from RF measurement and apparent discharge quantity, that is, use RF signal to estimate the apparent discharge. In this paper, on the basis of the experiment model of metal protrusion,...
