| Abstract: | Considering the partial discharge characteristics of free metal particles under different applied voltage in GIS, a force analysis is made to free metal particles. Depending on the results of the analysis, the whole process of partial discharge of the free metal particles is divided into three stages. PRPD of the free metal particles is measured under different applied voltage using pulse current measurement. The partial discharge characteristics of the free metal particles are analyzed, based on which the theoretical development process of the free metal particles is verified. |
