sulfur hexafluoride protection abb cost

sulfur hexafluoride protection abb cost2013/11/28SF 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.

The insulation associated with the several parts of the equipment must not only withstand the normal operating voltage, but also the higher surge voltage that may find its way into the equipment. So, while the insulation of the several parts is kept nearly equal, that of certain parts is deliberately made lower than others; usually this means the bushing.

Many of the methods described in this article can be performed as an acceptance or maintenance test, depending on conditions such as the test voltage applied or duration of test. The objective of any diagnostic test is to identify problems that may exist with a cable in a non destructive way so that preventative measures can be taken to avoid potential failure of that cable when in service.

General Properties of Sulfur HexafluorideUses of Sulfur HexafluorideMajor Application AreasIt is a colourless, odourless, tasteless, non combustible gas. It is liquefied under its vapour pressure when sent to another location. Contact with the gas may lead to frostbite. While exposed to fire or heat for an extended period, there's a possibility of rupturing the container with great sound. The estimated lifetime of SF6is in the range of 800 3200 years. 1.
