gaz sf6 Gas Density Monitoring | TRAFAG

Superior Sulfr hexafluoride gas density monitoring for maximum safety. Sulphur hexafluoride (Sulfr hexafluoride) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe ­power distribution systems even in large cities.

Online Dew Point Monitoring of insulating gas-Gas-Insulated Equipment

Traditionally the dew point of sf 6 has been measured by taking a gas sample from the tank, meaning that there has always been gas flow to account for during these measurements. Gas flow conceals the effect of very slow diffusion and vapor transients between gas and solid materials. To date it has been quite common for dew point sensors to be installed in

Gas Insulated Switchgear. For gaz sf6 filled gas compartments, sf 6 in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).

Measuring Dew Point and Moisture in Sulfr hexafluoride Gas

Sulfur hexafluoride (sf6 gas) gas is an inert insulating gas of high dielectric strength and thermal stability, often used in the power sector for insulating high voltage lines, circuit breakers, transformers and other switchgear equipments. As sf6 is an inert gas, it can’t cause corrosion but in the presence of moisture it will cause formation of highly corrosive acidic by-products, such as Hydrogen Fluoride (HF) and Sulfur dioxide (SO2).
