Particle traps constructed on the insulator of conductive slip rings for surface flashover mitigation under particle adhesion

open access: yesAIP Advances
The generation of abrasive particles is an unavoidable consequence of sliding electrical contact wear in conductive slip rings (SRs). The adhesion of abrasive particles to the insulators may lead to a decrease in flashover voltage, posing a risk to ...

Arc mapping [PDF]

open access: yes, 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.

Statistical Analysis of Flashover

open access: yesFire Science and Technology, 1982
Many successful fire tests were carried out so far and are now being accumulated as the data base which can be analysed statistically by an electric computer. In this paper, by statistically analysing such accumulated fire test data, the effects of the variour factors on the flashover time and the presence of flashover in fire spread process are ...
