Impulse Flashover Tests at

, 2006
the last decade. All are believed to be the result of lightning strikes to the antenna. The insulators that failed are fiberglass-belted safety core insulators that had been installed in the late 1990s. An investigation into these failures was undertaken

Pengaruh kelembaban terhadap Tegangan Flashover AC Isolator Piring

, 2012
Isolator piring banyak digunakan pada jaringan transmisi hantaran udara. Karena berada di ruang terbuka permukaan isolator dilapisi dengan polutan yang berasal dari udara disekitarnya sehingga tegangan flashover AC-nya dipengaruhi oleh kondisi udara di ...

Flashover studies on a solid dielectric surface

, 1991
Solid-gas interface in a high voltage insulating system is often subjected to highly localised critical electrical stresses leading to microdischarges and subsequent surface flashover.

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.

Clarifying the mechanism of flashover from the view of unburned fuel volatiles and secondary fuels

, 2014
[[abstract]]Several definitions of flashover exist. According to thermal theory, flashover occurs because of thermal instability in the upper hot layer of a fire compartment. The upper layer is particularly important.

Dependence of flashover on temperature and aspect ratio of the compartment

, 2003
A non-linear model of flashover, FLASHOVER A1, has been used to explore the dependence of the critical fire size necessary for the onset of flashover on the aspect ratio of the enclosure.
