Flashover: A Study of Parameter Effects on the Time to Reach Flashover Conditions
Volume 5: 17th Computers in Engineering Conference, 1997Abstract Flashover is characterized by the rapid transition in fire behavior from localized burning of fuel to the involvement of all combustibles in the enclosure. The objective of the present contribution is to calculate the development of flashover in a typical single room fire, and show the effect of ten key parameters on the time ...

Suppression Measures of Insulator Flashover Caused by Haze Flashover
2018 China International Conference on Electricity Distribution (CICED), 2018Fog haze weather frequently appears in recent years. Fog haze not only makes the travel inconvenient, also has a harmful effect on body. Fog haze brings serious security hidden danger to the power grid safety and power equipment operation. The lightest situation is shortening the time of saturated salt density, and pollution accident is the heaviest ...

Time to flashover characteristics and flashover mechanisms of a liquid film
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1980, 1980The origin of the phenomenon under study is the problem of flashover of high voltage polluted insulators,1 where a discharge elongates at the surface of a conducting film created by pollution deposition and humidification. The process ends up in a complete short circuit of the insulator.

Vacuum, 1977
It is shown that vacuum flashover is due to one or another process alternatively: (a) a thermal breakdown in the thin pre-surface layer of dielectric and (b) a streamer discharge in the desorbed gas cloud. The thermal flashover is observed in dielectrics with ρ v ≤ 10 11 -10 12 Ω cm under dc voltage.

Flashover of a Liquid Conducting Film Part 1: Flashover Voltage
IEEE Transactions on Electrical Insulation, 1982We have studied the phenomenon of flashover in a configuration related to that of flashover of high voltage insulators under polluted conditions: a glow discharge is struck at the surface of a liquid, and if the applied voltage is above a critical value, flashover occurs.
