  • Impulse Surface Charging and Flashover | SpringerLink

    In compressed-gas-insulated equipment, the weakest point in the system is often at the interface between the gas (usually SF 6) and the solid spacers used to support the conductors 1. The low dielectric strength is often attributed to the effects of surface charges, or to ionisation at high-field sites such as the gas-electrodeCited by: 2
