Integrated modelling of vacuum flashover development: Above‐surface processes and breakdown threshold analyses

High Voltage
The flashover in vacuum is a rapid interfacial discharge across the insulator surface when subjected to high applied voltage. Here a theoretical model covering above‐surface processes is introduced. The model calculates the flashover threshold in vacuum,

Surface flashover under RF and unipolar excitation at atmospheric conditions

, 2006
In vacuum environments surface flashover events driven by RF (f < 10 GHz) and unipolar excitation have been shown to have virtually identical dominant mechanisms.

, 2010
Establishing a compartment fire's area of origin when it has been burning at post-flashover conditions is a difficult process. Burn patterns traditionally used by fire investigators following post-flashover fires can be erroneous.
