Ultra-Trace Analysis Technique for insulating gas Using Gas

IntroductionProperties of sf6 gasExperimentalResultsDiscussion and ConclusionsAcknowledgmentsA tracer gas, by definition, can be any substance that does not have a significant background presence in the region being investigated. Tracers must also be non-toxic, non-allergenic, chemically inert, odorless, tasteless, non-flammable, non-explosive, easily transported, easily dispersed, easily sampled, quantified with high reliability, measured with repeatability and economical to deploy (1, 2). Sulfur hexafluoride (gaz sf6), halogenated compounds and perfluorocarbons are examples of such substances, which are also, incidentally, the most commonly used tracer gases. Tracers have been applied in a large variety of study areas including commercial heating, ventilating and air conditioning, atmospheric transport, pollutant dispersion, geological reservoir monitoring and underground mine ventilation to both qualitatively and quantitatively characterize various types of suspended, turbulent flows such as atmospheric currents and air stream movements where traditional practices were impra...Get price

Myth About sf6 gas Gas In Electrical Equipment

Where is Sulfr hexafluoride used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is Sulfr hexafluoride a health hazard? Pure Sulfr hexafluoride is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is sf 6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of sf6 gas used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
