Dew Point Calculator 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 ...

GIS and hybrid switchgear technology - Energize above approach requires minimal consumption of SF6 gas as only VCB and DS is only in SF6 gas unlike conventional GIS switchgear where all HV compartments are in SF6. By using this approach, the SF6 consumption is reduced to 1,5 kg for up to 24 kV and 4,5 kg for 36 kV switchgear respectively.
