SF6 also lasts in the atmosphere for more than 3,000 years after it is released. As an excellent insulator, SF6 is often found in gas-insulated switchgear (GIS), equipment used in high-voltage electrical systems to control the flow of electrical current. SF6 routinely leaks into the atmosphere from closures and joints in GIS equipment.SF6 gas in medium-voltage switchgear | T&D Guardian ...

M-Series STATCOM, a Voltage source converter (VSC) based modern compensation system, can act as a source or sink for reactive power. It consists of a controllable part that can operate as capacitive and inductive power and keeps the reactive power flow constant in the system.People also askWhat is a STATCOM reactor?What is a STATCOM reactor?A STATCOM is a voltage source converter (VSC) based device, with the voltage source behind a reactor. The voltage source is created from a DC capacitor and therefore a STATCOM has very little active power capability. However, its active power capability can be increased if a suitable energy storage device is connected across the DC capacitor.STATCOM – Working Principle, Design and Application ...

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas, and an excellent electrical insulator. [4] SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents.Sulfur hexafluoride - Wikipedia
