filter SF6 газ humidity

The cavity inside the filter cap is designed so that the volume between membrane and sensor is negligible; hence the impact on response time for humidity measurements is reduced to a minimum. The cap is available in white and is made of a single piece of polypropylene (PP) and a filter membrane welded to the single piece.

  • Drying and particle filters absorb moisture, gas and dust

    On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.

  • The Problem with Humidity in SF6 Gas-Insulated Systems

    To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.

  • SF6 Gas Dehydration System That Doesn’t Require Downtime

    Created in partnership with a European utility company, WIKA’s revolutionary GAD-2000 not only removes humidity from SF 6 gas and dehydrates the compartment itself, but it does so while all the equipment is still online. Sulfur hexafluoride (SF 6) is an excellent dielectric insulator, commonly found in medium- and high-voltage electric switchgear. The non-flammable gas is a potent arc quencher: In the high-heat environment of an electrical discharge, the six fluorine atoms split from the

    -49,5 °C at 226 kPa (2.26 bar). So when measuring humidity in terms of frost/dew point in the typical SF 6 range (-3…-60 °C) using a chilled mirror hygrometer, there is clearly a risk that an optically detected condensate layer could be SF 6. From a humidity perspective this adds a potentially significant measurement uncertainty,
