FLASHOVER PROTECTION DEVICE AND METHOD: WET/DRY GLOW-BASED STREAMER INHIBITOR

摘要

A device and method for reducing the risk of a streamer initiated flashover across a high voltage insulator under normal operating voltages. The device include s a support structure adapted to be grounded and mounted in proximity to the hig h voltage insulator; and space charge producing conductors wound around the support structure and forming coils for producing space charge in a proximit y of an insulator to be protected, and inhibiting a formation of positive streamers, each conductor having a diameter not exceeding 0.1 mm for reducing a corona inception voltage of the support structure upon which each conductor is woun d, in both dry and wet conditions.
