The crossing points of the A([U.sub.0]) relations with the line representing the voltage breakdown condition (4) define the maximal distances, at which flashovers occur.
These results are in contradiction to the lightning protection standard [11], where it is stated that dangerous sparking or flashovers should be attributed to the subsequent negative lightning strokes.
Thus, the typical flashover scenario, wet film layer with an increased leakage current, dry band arcing, bridging of individual insulator sheds and finally the electrical flashover, is impossible.
The vital signs monitoring and flashover detection technologies sprung from the initial kernel of the idea for a first responder locator, Mr.
The closest to becoming a reality is the vital signs monitor, while the flashover detection technology is estimated to be four years from completion.
He's in demand as a speaker at electrical conferences across North America and is recognized as an expert on corona discharge and flashovers. Most of his time, though, is spent underground as the mining industry's preeminent dustbuster.
Most flashovers, he explained, are caused by corona discharge.
While acknowledging that "we have had damaged airplanes" due to Kapton flashovers, David Pielmeier, the Navy's top wiring engineer, said the service banned it in new planes because of concerns it would explode in combat, not in peacetime use.
But more recently, in tests and in the field, Kapton has been found susceptible to a phenomenon known as "flashover." Worn or otherwise damaged wires can produce an arc-a ribbon of current between exposed wires.
At many of the test sites, arcing and flashovers had been causing frequent outages, up to once a month.
Staff demonstrated how conditions such as flashovers and back drafts can result in terrifying fire balls.
In the 1970s, Dow Coming developed a room-temperature curing elastomer, designed for spray application to porcelain insulators to reduce insulator maintenance and resist flashovers, particularly in salt fog environments.
Cadet William Mott, aged 15, of 121 (Nuneaton) Squadron said: "We all had a go at extinguishing some fairly serious fires but the most spectacular part of the training came when we were able to view at close quarters, a demonstration of the consequences of flashovers and front and side backdrafts.
Changes in building techniques - such as the proliferation of double glazing - have increased the risk of fire getting out of control in the form of terrifying backdrafts and flashovers. Radford Road fire station in Coventry is at the forefront of revolutionary new training techniques to combat the problem using the area's only flashover simulator.
