A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges . Dielectric gases are used as electrical insulators in high voltage applications, e.g. transformers , circuit breakers (namely sulfur hexafluoride circuit breakers ), switchgear (namely high ...
Dielectric materials can be solids, liquids, or gases. (A high vacuum can also be a useful, [ 23 ] nearly lossless dielectric even though its relative dielectric constant is only unity.) Solid dielectrics are perhaps the most commonly used dielectrics in electrical engineering, and many solids are very good insulators.

6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. The high dielectric strength is a result of the gas's high electronegativity and density. This property makes it possible to significantly reduce the size of electrical gear.
Dielectric liquids are divided into single- and two-phase applications, which differ in whether or not the cooling fluid turns into a gas during the cooling cycle. Single-phase immersion uses a circulation method for the dielectric liquid across hot electronic components and to a heat exchanging approach.
If the dielectric happens to be a solid, permanent physical and chemical changes along the path of the discharge will significantly reduce the material's dielectric strength, and the device can only be used one time. However, if the dielectric material is a liquid or gas, the dielectric can fully recover its insulating properties once current ...
Quebec provides about a quarter of Vermont's hydro power, a third of its heating oil, kerosene, propane, diesel fuel, and gasoline, and 100% of its piped natural gas, Cota said.
An additional process when using chlorine gas for removal of bacteria and organic contaminates in drinking water supplies. [22] Treatment of public swimming baths, aquariums and fish ponds involves the use of ultraviolet radiation produced when a dielectric mixture of xenon gas and glass are used. [23] [24]
