The influence of SF<sub>6</sub>-admixtures to N<sub>2</sub> on electrodeless streamer inception at the surface of a dielectric solid (epoxy resin) is investigated for different SF<sub>6</sub>/N<sub>2</sub> ratios and gas pressures, with focus on the lower pressure region (below 1 bar) which is only sparsely discussed in literature. For this purpose, we use(More)
When charged particles impact the surface of a solid material, they can be backscattered from that surface or cause secondary electrons to be emitted. The ratio of the number of emitted electrons (secondary and backscattered) to the incident electrons number is known as the total electron emission yield. Knowledge of this total electron emission yield(More)
Summary form only given. Sulfur hexafluoride (SF<sub>6</sub>) is commonly used as a gaseous dielectric in high-voltage equipment due to its excellent insulating properties and chemical stability. However it significantly contributes to the greenhouse effect, and can under certain circumstances (after a discharge event) be poisonous for persons. Therefore,(More)
