Why the EU should ban SF6 | Agile Energy Recovery Ltd regulation's aim is to bring down the EU's F-gas emissions by two-thirds from 2014 levels by 2030 as part of the ultimate objective of cutting overall greenhouse gas (GHG) emissions by at least 80% by 2050 against 1990 levels (Biasse, 2014).
Green Gas for Grid - g3 - SF6 Free Solutions 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.
GIS | High-Voltage Gas Insulated Switchgear Substations Insulated Substations . A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible.
