Get PriceThis international standard specifies the quality requirements for sulfur hexafluoride (SF6) of technical purity and for complementary gases such as nitrogen (N2) and tetrafluoromethane (CF4) (also tetrafluorocarbon) for use in electrical equipment. Analysis methods based on both measurement equipment for laboratory testing and on-site testing for the analysis of SF6, N2 and CF4 gases before these gases are filled into electrical equipment are also described in this document.
Get PriceIncreased safety, cost reduction and climate protection. When insulating switchgear or transformers, sulfur hexafluoride (SF6) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dr ger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.
