    Nov 01, 20181.2.Greenhouse effect of SF 6. SF 6 gas is considered as one of the most harmful kinds of atmospheric greenhouse gases (Xiaoxing et al., 2013b).Its global warming potential (GWP) is 23,900 times higher than that of CO 2, and the life span of this gas is 3400 years in the atmosphere (Xiaoxing et al., 2013b).Global warming, ozone depletion, and drastic reduction of biological species are known

  • Partial discharge behaviour of SF6 substitute gases for

    The aim was to evaluate the effect of SF6 alternative gases on the partial discharge characteristics and study the effectiveness of different monitoring systems. This research was carried out with a view to developing more eco-friendly, SF6-free, Direct Current Gas Insulated Switchgear (DC GIS).

  • Investigation on pulsed discharge mode in SF6-C2H6

    Feb 07, 2020The non-chain chemical HF(DF) laser is one of the most powerful electrically-driven lasers operating in mid-infrared, in which SF 6-C 2 H 6 mixtures are often used as lasering media. Due to the electronegativity of SF 6, the discharge in SF 6-C 2 H 6 presents a complicated discharge mode. To achieve reproducible pulsed laser output, pulsed discharge in SF 6-C 2 H 6 mixtures is investigated

  • Green gas for grid as an eco-friendly alternative

    The results indicated that the discharge inception voltages in g3 gas were 90.1-92.5% of that in SF 6. In two particles, PD occurred with higher average apparent charge and discharge repetition rate in g3 compared with those in SF 6 gas. The time-resolved partial discharge presented similar characteristics in g3 and SF 6 gas. The time interval

    Under this protocol, SF6 gas also has to be reduced and therefore appropriate action is needed worldwide to replace SF6 gas by environmentally friendly gases or gas mixtures. Due to the above reasons, investigations are in progress to develop alternative methods to minimize the release of SF6 into the environment. Possible solutions

  • Dielectric gas - Wikipedia

    A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges.Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers), switchgear (namely high voltage switchgear), radar waveguides, etc.
