SF6 insulating installations are today the most performing technical solution applied to high voltage devices such as circuit-breakers and surge arresters. This gas is used due to a lot of excellent insulating properties. These properties are depending on many variables, one of them is electrodes? geometry and material. Generally, when studding the dielectric breakthrough process, ideal electrode surfaces are taken in consideration. But many experimental results, different than theoretical ones, could be a consequence of microscopic asperities. This paper presents a theoretical synthesis of this dependence,combined with some experimental results. All measurements were carried out at the High Voltage Laboratory, from the POLITEHNICA University in Timisoara, Romania. All data processed are in relation with the real situation of a capsulated switcher or a capsulated high voltage surge arrester, existing in service. This study can also limit the effects of environmental pollution with insulating gases.
