  • Portable SF6 leak monitor, SF6 Leakmate with selectable

    The SF 6 Leakmate, portable SF 6 leak monitor is a great device for mobile SF 6 leak detection. In practical use, it has a detection threshold of 1 x 10E-6 mbar l/s, which makes it perfectly suitable for simple leak detection applications on SF 6 switchgear. The easy to use, processor controlled portable SF 6 leak monitor, features both an audible alarm and an LED bar graph display, allowing estimation if a small, medium or big leak is being detected.

    The decomposition characteristics of SF6 under four types of negative DC partial discharge (DC-PD) are obtained. The relationship between the decomposition characteristics of SF6 and the PD types was further studied. Moreover, back propagation (BP) neural network algorithm [29–38] is used to recognize the PD types.

  • 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 % (*).
