Interactions between SF6 and water exposed to γ radiation or to partial discharges

In order to determine more exactly the water influence in the decomposition mechanisms of SF
6
under different kinds of stresses SF
6
-H
2
O mixtures have been exposed to y radiation (
⁶⁰
Co γ-rays) and to partial discharges (point-plane electrode configuration). In these mixtures the SF
6
pressure was about one bar and the water content varied between 1 000 and 10 000 vpm. The experiments have been carried out at room temperature.
