  • SF6-alternative gases for application in gas-insulated

    Mar 20, 2018The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases.

  • End-of-life factors in high voltage gas insulated

    Jul 06, 2020If application of non-SF6 gases and gas mixtures requires different high-speed earthing switch design the impact on mechanical or electrical wear should be discussed between the end user and the equipment manufacturer. Besides visual inspection, resistance test, timing tests and travel curve measurement may be useful for assessment of the device.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

  • Thermal Recovery Characteristics of a CO 2 Mixture Gas

    The results had been calculated for the initial filled pressure of SF6 0.5 MPa and CO2 1.0 MPa. Although the initial pressure of the CO2 mixture gas was higher than that of the SF6 gas, its post-arc current value is high. Fig. 3.Example of post-arc current for the final model interrupter (SF6: 0.5 MPa, CO2: 1.0 MPa) 3. Tests and Results

  • Mositure testing in GIS - Electric power transmission

    The partial pressure of water vapour in atmospheric air can be quite high and the desired partial pressure on the dry gas side of the system remarkably low. Water is a very small molecule compared to SF6, which means that, for a given temperature, the average speed of water vapour molecules is much higher than that of those of the rest of the gas.
