High voltage vacuum interrupter electric field distribution. QuickField FEA simulation example

A Simulation Analysis to Improve the Dielectric Strength Inside High Voltage Vacuum Interrupters. This example https://quickfield.com/advanced/high_... is inspired by Karthik Reddy Venna dissertation https://opus4.kobv.de/opus4-btu/front... Metal shields between the ceramic blocks of the interrupter body protect the ceramic from the metal vapor deposition during the arcing process. But they also influence the electric field distribution and may decrease the dielectric strength of the device. So a detailed analysis of the electric field is required.
