GE SF6 dew point

Dec 08, 2020 · Dew point and relative humidity are not the same, but they are closely related: the higher relative humidity is, the closer the dew point is to the current air temperature. In a particular case, when the air is maximally saturated with water (the relative humidity is 100%), the dew point is equal to the current temperature.

  • Measuring Dew Point and Moisture in SF6 Gas

    Most Gas Insulated Equipment (GIE) manufacturer recommend minimum and maximum tolerances for certain variables within the gas, including moisture, gas decomposition, and purity of SF6. A typical dew point range for servicing the SF6 equipment is -50…-20 °C. Pure SF6 may be even drier.

    Dew is the condensed water that a person often sees on flowers and grass early in the morning. Dew point varies depending on the amount of water vapor present in the air, with more humid air resulting in a higher dew point than dry air. Furthermore, the higher the relative humidity, the closer the dew point to the current air temperature, with 100% relative humidity meaning that dew point is equivalent to the current temperature. In cases where dew point is below freezing (0°C or 32°F

  • Dew point - Wikipedia

    The dew point is the temperature to which air must be cooled to become saturated with water vapor. When cooled further, the airborne water vapor will condense to form liquid water . When air cools to its dew point through contact with a surface that is colder than the air, water will condense on the surface.
