Numerical simulation of negative point-plane corona ...· The negative corona discharge model investigated in this work is a 2D axisymmetric point-plane geometry. The gap between both electrodes is filled with SF 6 under a pressure of 0.4 MPa. The geometry is the same as in the authors' previous work [].The computational domain is chosen to be 30 mm × 36 mm—the same size as that investigated in air [13, 24].
Rexon Automatic SF6 Synthesized Tester The RN500SF6 Synthesized Tester is a set of SF6 trace moisture test, SF6 purity test and SF6 gas decomposition product test, which integrates the functions that can be realized with three instruments in one. All the indicators can be tested in one field measurement, which greatly saves the gas in the equipment, reduces the user's workload and improves the work efficiency.
GIS or Gas Insulated Switchgear | Electrical4U· SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.

SF6 (Sulfur Hexafluoride) Recovery | Hudson Technologies is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.
Panel discussion: The pros and cons of using SF6 gas in ... 6 gas is considered as a greenhouse gas, consequently release of the gas into the atmospheres should be minimised or avoided. At the end of switchgear life, the gas should be recycled and switchgears should be designed to ensure leaks are minimised as far as possible. Appropriate designs are required for easy filling and collection.
