Modelling vacuum flashover mitigation with complex surface microstructure: mechanism and application
Publikováno v:
High Voltage (2020)
The vacuum discharge along the dielectric surface, also called surface flashover, brings significant damages to the vacuum-solid insulation system. Here the authors implement shape-flexible, complex surface groove microstructures on the dielectric to

Surface charging of typical space materials such as polyimide and high density polyethylene may sometimes cause electrostatic discharge (ESD) under natural conditions. That is because polymer materials usually present lower surface discharge strength
