17/04/2018Sulfur hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).

08/11/2021A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

24/09/2020The system consists of a SF 6 (sulfur hexafluoride)-free gas-insulated high-voltage switchgear (GIS) called 8VM1 Blue GIS and a liquid-immersed distribution transformer with ester fluid. It is part of a demo project by Shanghai Electric, located at Shantou Haojiang onshore Industrial Park on the east coast of Guangdong, South China.

A pump or fan load is a variable torque load. A variable torque load varies by the cube of the speed. A 50 Hz motor operating on 60 Hz will attempt to rotate at a 20% increase in speed. The load will become 1.23 (1.2 x 1.2 x 1.2) or 1.73 times greater (173%) than on the original frequency.

The Multi-Analyser SF6 is a battery-operated, compact, user- and maintenance-friendly device which guarantees high measuring accuracy. The unit allows diu001ffferent kinds of measurements and treatment of the measured gas in one of the following ways: a pressure reducer is not needed. If the gas should not be pumped back into the SF 6 filled

new type sf6 Alternatives safety precautions in Sweden20/10/2020There are some strong motivations for transitioning away from SF 6 to an innovative new alternative that uses only pure air: #1: Pure Air is Superior to a Strong Greenhouse Gas. SF 6 has a global warming potential (GWP) 23,500 times greater than that of CO 2. The GWP metric was developed to compare the global warming impacts of different gases.

Since SF 6 is a major greenhouse gas with high global warming potential listed in the Kyoto protocol, it is among the six gases subject to monitoring. SF 6 has to be used in closed systems in order to avoid emissions. For over 50 years, we have been preferred supplier of devices and equipment for emission-free SF 6 gas handling.

Subaru's FB25 was a 2.5-litre horizontally-opposed (or 'boxer') four-cylinder petrol engine. Effectively replacing the EJ253, the FB25 engine was a member of Subaru's third generation 'FB' boxer engine family which also included the FB20, FA20D, FA20E and FA20F engines.The FB25 engine first offered in Australia in the 2011

In the occurrence of arc discharges, spark discharges and corona discharges, SF6 can react with very little water, air, electrode and solid insulated material. Producing a byproduct include carbon tetrafluoride (CF4), thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), and sulfur dioxide (SO2), along with solid byproduct including aluminum fluoride, tungsten fluoride.
