Solid-gas interface in a high voltage insulating system is often subjected to highly localised critical electrical stresses leading to microdischarges and subsequent surface flashover. Such a failure at the interface is of serious concern in a high voltage system. This paper presents results of the power frequency and impulse flashover studies carried out in air on a solid dielectric surface in a non uniform field with air as the surrounding media. The influence of humidity on the power frequency flashover voltages on a solid dielectric surface is also discussed.
