Impact of sf 6Condition-Based Maintenance Asset Strategy'Real-Time' Condition-Based Maintenance StrategyChange For Climate ChangeAccording to the Intergovernmental Panel on Climate Change, Sulfr hexafluoride is the most potent greenhouse gas that it has evaluated, with a global warming potential of 23,900 times that of CO2 when compared over a 100-year period [1 Appendix 1]. All developed jurisdictions require the annual reporting of insulating gasusage . Sulfr hexafluoridetoday contributes less than 1 percent of man made global warming, although is increasing annually . sf6 gascircuit breakers typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies. Over time, seals degrade due to environmental conditions and exposure. The IEC 'default annual leakage rates' of gaz sf6for a single 'gas insulated switchgear and circuit breaker applications' is 0.0089 (i.e. less than 1%) . Major manufacturers have demonstrated leakage rates below 0.1% per year, following decades of operational experience and extreme temperature testing .
