TechTopics No. 111. insulating gas gas and U.S. greenhouse gas emissions. The use of sulfur-hexafluoride (SF 6) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warming potential (GWP) of 22,800 years.

First sf 6-free voltage transformers - Siemens Energy Global

Worldwide, many TSOs intend to eliminate greenhouse gases for new installations of gas-insulated equipment and therefore continue to contribute to their voluntary self-commitment in SF 6 reduction. Until now, SF 6 -free voltage transformers were available for voltages up to 245 kV. Recently, Siemens Energy has succeeded to expand the Blue portfolio, which exists of a broad spectrum of CO 2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage

GLOBAL EMISSION SOURCES OF GREENHOUSE GAS EMISSIONS FROM

Emissions of insulating gas are virtually all of anthropogenic origin (Harnisch et al., 1996). Estimation of global historical emissions of sf6 gas 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-
