  • Decomposition Characteristics of SF6 and Partial Discharge

    Tang et al. compared and analyzed the decomposition characteristics of SF6 under two types of common PDs [20], and recognized four typical PD types [21,22]. A large number of studies have shown that the type, concentration, and formation law of SF6 decomposed components are closely related to the type and severity of insulation faults in GIE.

  • SF6 Decomposition in Gas-Insulated Equipment - IEEE Journals

    Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 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 a health hazard? Pure SF6 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 SF6 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 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 % (*).

  • Mechanism of Formation of SF Decomposition Gas Products and

    reaction of decomposition products with water and oxygen are shown in Fig. 2. It can be seen that the major products of the decomposition reaction are sulphur oxides, while others are fluoride compounds. The concentrations of decomposition products are directly dependent on spark conditions and energy. Figure 2. The formation of SF 6
