Statistical Analysis of Flashover

Fire 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 ...

Study on the dc flashover performance of standard suspension insulator with ring-shaped non-uniform pollution

High Voltage, 2018
Under dc electric field, pollution may be more easily deposited around insulator string caps and pins, distributing non-uniformly on its inner and outer parts, and presenting ring-like shape.

Creeping flashover characteristics improvement of nanofluid/pressboard system with TiO2 nanoparticles

AIP Advances, 2018
Creeping flashover easily occurs at the interface between oil and pressboard in transformer and thus results in outage of power transmission system. Investigations have shown that creeping flashover characteristics at oil/pressboard interface can be ...

Flashover and Transformer Voltage

IEEJ Transactions on Industry Applications, 2010
This thesis stated many examples about transformer voltage on the direct current motor and generator that those were measured. They suggest that a flashover occurrence often has an indirect influence.

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

AIP 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 ...
