Characteristics of EMI generated by negative metal-positive dielectric voltage stresses due to spacecraft charging [PDF]

, 1985
Charging of spacecraft surfaces by the environmental plasma can result in differential potentials between metallic structure and adjacent dielectric surfaces in which the relative polarity of the voltage stress is either negative dielectric/positive ...

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,

Arc mapping [PDF]

, 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.
