This paper describes insulation technology for 72/84 kV vacuum interrupter for a new cubicle-type gas insulated switchgear (CGIS). The insulation performance has been increased significantly by a multi-gap shield configuration around the ceramic surf

The electrical characteristics of a wire discharge plasma were investigated, in particular, taking notice of the effect of electron trapping by axial magnetic fields. It was found that the plasma property changed remarkably, when the magnetic fields

The authors carried out shunt capacitor switching tests on 24 kV model vacuum interrupters with contact materials CuW and CuCr. The restriking probability of the contact material CuW is lower than that of CuCr. The contact material CuW is also an exc

High-current interruption experiments were carried out on low-surge contact material Ag-WC set in axial magnetic field electrodes. The most influential factors on high-current interruption are the contact material, the axial magnetic field, and the i
