Vacuum Arc Ion Flux From Vacuum Interrupter Contact Gap [PDF]

open access: yesPLASMA PHYSICS AND TECHNOLOGY, 2017
Dielectric properties of vacuum interrupters are influenced by metal vapour deposition on the inner ceramic surfaces. Therefore these surfaces are partly protected by shield electrodes. The metal vapour originates from the vacuum arc in the contact gap during switching off process.
