Electrical Circuit Flashover Model of Polluted Insulators Based on this criterion, a new distributed parameter electrical circuit flashover model of polluted insulators is presented. The arc channel is considered as an equivalent distributed parameter circuit model instead of using the arc voltage-gradient equation. The parameters of the arc model are obtained from the electromagnetic field
Flashover - an overview | ScienceDirect TopicsWhile surface flashover in vacuum is generally undesirable, it is necessary for the operation of triggered vacuum gaps, i.e. the “switch” for many pulse power systems. Much has been written about the mechanisms by which triggered vacuum gaps operate and many ingenious designs have been described [–].By way of illustration, we shall describe a recent
