Abstract

Conducting particles in transmission and switching equipment insulated by compressed sulphur hexafluoride (SF₆) can result in loss of as much as 90% of the gas dielectric strength. Particles in practical systems can exist in a wide variety of shapes and sizes, and of materials of different densities. In this paper, the effect of particle size on the probability of SF₆ breakdown is discussed. Theoretical and experimental results are presented.
