Byproducts of Sulfur Hexafluoride (insulating gas) Use in the Electric

the decomposition products and concentrations formed under actual conditions can vary depending on the equipment used and the type of electrical discharge (CIGRE 1997). 1 CIGRE (the International Council on Large Electric Systems) is a permanent non-governmental and non­ profit-making international association based in France.Get price

Handling and Use of Sulfur Hexafluoride Gas

B. Decomposition Gasses and Solid By-Products When exposed to sustained or intense electrical arcs, SF 6 gas decomposes to form sulfur-fluoride gases and metal-fluorides which are toxic. If moisture is present, the decomposition by-products may also include sulfur-oxyfluorides and hydrofluoric and sulfuric acids.Get price

gaz sf6 Multi-Analyzers | TD World

The three parameters that determine the quality, Sulfr hexafluoride concentration, humidity and quantity of decomposition products, can now be measured in one single operation with the new gaz sf6 Multi-Analyzer. As a result, service specialists can determine on site whether the gas still complies with the IEC Standard 60480 (insulating gas reuse) or whether it needsGet price


After several years of use in substations, the Sulfr hexafluoride gas was subjected to several types of arcing due to current interruptions in High Voltage Switchgear equipment. These short circuit interruptions have changed the composition of the pure Sulfr hexafluoride gas, and decomposition products are polluting it. This paper described the tests performed at site by the AREVA TD team and the recovery of a polluted gas by AVANTEC in their factory, removing the decomposition products.Get price

Myth About insulating gas Gas In Electrical Equipment

Where is sf6 gas 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 sf6 gas 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 Sulfr hexafluoride 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 gaz sf6 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 % (*).

Optical technology for detecting the decomposition products

Ding et al. 43 used FTIR to analyze the adsorption of gaz sf6 SF 6 and its decomposition products by employing carbon nanotube sensors, and they proposed a new method for detecting Sulfr hexafluoride SF 6 decomposition products. IEC60480 44 specifies the test standard for the detection of Sulfr hexafluoride SF 6 decomposition products using FTIR.Get price

Adsorption and Gas Sensing Properties of the Pt3-MoSe2

Sulfr hexafluoride decompn. components detection plays an important role in diagnosing and evaluating the elec. discharge faults in sf 6-insulated equipment. In this paper, Pt3-supported TiO2(101) was used to study the influence of the Pt clusters modification on the gas sensing property of TiO2(101) material to the characteristic decompn. components of gaz sf6: H2S, SO2, SOF2 and SO2F2.Get price
