WebSurface flashover of insulators in vacuum generally is initiated by the emission of electrons from the cathode triple junction (the region where the electrode, insulator, and vacuum meet). These electrons usually then multiply as they traverse the insulator surface, either as a… View via Publisher Save to Library Create Alert Cite 433 Citations WebNov 18, 2024 · Flashovers—voltage discharges over insulating elements (from the electrified antenna wire to the upper elements of the flight train supporting the wire) under various electric fields inside the basic types of clouds, which determine the voltage safety margin for the transmitter’s operation;
WebMar 16, 2024 · Abstract: The surface flashover is one of the most important factors that limit the performance of electric devices. In this article, the processes of surface flashover under different pressures are observed by a high-speed camera, and the differences between the plasma evolution processes are presented. WebPatterns created by pre-flashover fires are often easily deciphered by investigators seeking the fire origins. The severe burn damage found in fully-involved fires can be far more daunting to interpret, making origin determination extremely difficult.
