SF6 decomposition leak rate abb

Feb 26, 2015CIGRE WG 23.10 is working on an SF6 recycling guide, covering purity criteria for SF6 SWG. Criteria for handling of SF6 are based on IEC 376 Standards for safety of personnel and environment. These factors contribute in minimizing emissions to the atmosphere. The normal leakage rate of HV Switchgear can be expected to be 0,1 % - 0,5 % per year.
