GLOBAL EMISSION SOURCES OF GREENHOUSE GAS EMISSIONS FROM

Emissions of Sulfr hexafluoride are virtually all of anthropogenic origin (Harnisch et al., 1996). Estimation of global historical emissions of Sulfr hexafluoride can be based on a survey of global annual sales per application conducted by an independent auditor, Science and Policy Services (S PS, 1997). In this survey, in which the six major manufacturers co-

Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. Sulfr hexafluoride has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses insulating gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.
