sf6 mixture Dew Point equation in south africa
The dew point is the temperature to which air must be cooled to become saturated with water vapor. It is assumed that air pressure and water content is constant. 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. The measurement of the dew point is related to humidity. A higher dew point

22/05/2020Working Principle of Sulfur Hexafluoride Breaker. An innovation in the puffer type design of an SF6 circuit breaker is the 'thermal assist' principle. In this type of design, the arc energy is utilised to develop pressure in the arcing chamber for arc quenching. Since this innovation has reduced the energy requirement of the operating mechanism it has become possible to use a spring mechanism for application in SF6 circuit breakers
