Flashovers on transmission lines
Electrical Engineering, 1936This paper is intended to be of practical use to transmission line engineers in that it shows how transmission line flashovers may be estimated and segregated into 1, 2, and 3 phase, and double circuit, flashovers. The method of calculation is comparatively simple and based upon analyses of statistical and analytical information.

Initiation of HPM Surface Flashover
2007 IEEE 34th International Conference on Plasma Science (ICOPS), 2007Summary form only given. Surface flashover formation at dielectric/air interfaces during pulsed high power microwave (HPM) excitation can severely limit the power densities which can be transmitted into atmospheric medium. Previous studies on HPM surface flashover in the S-band at 5 MW power levels have reported on the contributing factors to flashover

The main objective of the present study is to further our understanding of the influence of ambient temperature, freezing water conductivity and nature of applied voltage on the surface flashover of ice. Flashover tests were carried out using two metallic hemispherical capped rods 12 mm in diameter, separated by an ice surface. The distance between the

Flashover of a Liquid Conducting Film Part 2: Time to Flashover - Mechanisms
IEEE Transactions on Electrical Insulation, 1982A dc glow discharge at atmospheric pressure is struck at the surface of a liquid. If this dc voltage exceeds a critical value, flashover occurs, resulting in a short circuit of the liquid. Curves of time to flashover as a function of applied voltage for different liquid resistivities are given.

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

A Comparison of Flashover Theories
Volume 6: 18th Computers in Engineering Conference, 1998Abstract In structural fires, flashover is characterized by the rapid transition in fire behavior from localized burning of fuel to the involvement of all combustibles in the enclosure. Major parameters affecting flashover are fire growth rate, ventilation opening area, and room area.

A Fuzzy Framework for Flashover Monitoring
2005This paper presents a new analysis method of the leakage current on contaminated polymer insulators under salt-fog conditions. The proposed method tries to combine frequency-domain information with time-domain information using the framework of the fuzzy inference engine.

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...

Proceedings of the Institution of Electrical Engineers, 1968
This paper presents a review of published work on flashover, mainly of Russian, German and American origin. The information obtained from these sources, combined with supporting experimental work, enables a comprehensive explanation of the phenomena to be given. A list of running conditions for which flashover has been reported is given.
