Flashover inhibition by encapsulation
7th Pulsed Power Conference, 2005The utilization of high voltage electrodes in vacuum environments is common in a number of pulsed power applications. A limitation to voltage amplitude and/or pulse duration is flashover across the insulator separating the electrodes. Most often in cases where external effects are not involved, the cause of flashover is due to electron emission from ...

Considerations of Flashover Propagation
Journal of Spacecraft and Rockets, 2018Flashover propagation of plasma on a solar panel is considered from a physics standpoint. Although useful as a first attempt to describe the flashover phenomenon, the previous perimeter theory is s...

Post‐Flashover compartment fires
Fire and Materials, 1983AbstractFourteen mathematical models of post‐flashover compartment fires are classified on the basis of fourteen principal modeling aspects. Expressions are presented for the potential of fire to spread by destruction and convection. The assessment of the fire resistance requirements for the compartment boundaries is discussed and measures to counter ...

Estimation of surface flashover threshold in a vacuum II: flashover phase transition
Journal of Physics D: Applied Physics, 2019Surface discharge in vacuum occurs under intense external field, also called flashover. The flashover threshold over which surface flashover occurs is of vital importance in vacuum-solid interface. It is widely assumed that flashover is initiated by single surface multipactor and develops as a plasma discharge along dielectric surface, namely secondary

Estimating room flashover potential
Fire Technology, 1980Flashover is the ultimate event in a room fire signaling the final untenability for room occupants and greatly increased hazard to other building spaces. Despite this importance, hazard evaluations of furnishings and other common fuel loads have normally not been based on estimates of flashover potential.

Nature, 1976
THE increasing importance of vacuum insulation in technology1 and the recognition of the disruptive effects of surface discharges on satellites in space2 both impart fresh impetus to the understanding of the flashover effect. Solid insulators are certainly a source of gas in vacuo, particularly under bombardment, and can also cause local enhancement of

Surface flashover of insulators
IEEE Transactions on Electrical Insulation, 1989The author reviews surface flashover (i.e. voltage breakdown along the surface of insulators), primarily in vacuum. He discusses theories and models relating to surface flashover and pertinent experimental results. Surface flashover of insulators in vacuum generally is initiated by the emission of electrons from the cathode triple junction (the region ...

The recent visit of Dave Hammer from NRL gave me occasion to analyse roughly the available small sample flashover data and I thought the results might be of minor interest to others. This re-analysis has been directed towards the region of interest to tube designers and concentrated on perspex (i. e.
