  • SF6 Insulated Current Transformers – Trench Group

    SF 6 insulated current transformer are used to convert high transmission line currents (up to 6000 A) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system. As such, the need for accurate and reliable current transformation is essential. The reliability and security of Trench gas-insulated instrument transformers is based on over 50 years of innovation with gas-insulated units operating under a wide range of

  • Is SF6 Dissolved in Your Transformer Oil? - Doble Engineering

    A gas detector can be used to locate outboard SF 6 leaks, but how can one know if SF 6 gas is leaking through a bushing seal into the main transformer tank? Records from our dissolved gas analysis (DGA) laboratories indicate that approximately 0.3% of oil samples in North America contain traces of dissolved SF 6 gas. We expect this percentage is much higher in regions where GIS facilities are more common, including the Middle East, South America, and Japan, for example.

  • SF6 Circuit Breakers - TestGuy

    Advantages of SF6. SF6 has a number of advantages for use as an insulator. The dielectric strength of SF6 increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive.

  • Gas-insulated Switchgear (GIS) Testing - OMICRON

    Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS. The characteristics of the SF6 gas also allow the extinction of arcs which can occur during disconnection of live contacts.
