The vacuum interrupter (VI) uses the axial magnetic field (AMF) type electrode structure to secure the current interrupting performance in long contact gaps. The AMF electrode has contact support made of stainless steel (SUS) to improve mechanical st

An application of a functionally graded material (FGM) to the solid spacer in gas insulated switchgears (GISs) can reduce the electric field concentration at the specific region, for example, the anode or the interface between the spacer and the gas.

The shape of an arc shield in a vacuum interrupter (VI) is varied for the development of insulation. Through the experiment, the flashover voltage is estimated, and the computer-aided finite element method (FEM) is applied to observe the electric fie
