new type sulphur hexafluoride Measurement pdf

installation use sulphur hexafluoride gas (SF6) to extinguish the electric arc and as the insulating medium. Breaking in SF6 gas takes place without current chopping or generation of overvoltages. These characteristics guarantee a long electrical life for the circuit-breaker and limited dynamic, di-electric and thermal stresses on the installation.

  • Measurement of the diffusion coefficient of sulfur

    Abstract. Sulfur hexafluoride has been widely used in field studies and laboratory experiments to develop a relationship between gas transfer and wind speed. The interpretation of the data from such studies requires the diffusion coefficient of SF 6 ( DSF6 ), which has not previously been measured. In this study, DSF6 has been determined in pure water and in 35‰ NaCl over a temperature range of 5–25°C.
