develop Gas Insulated Switchgear check for leaks

A Gas Insulated Switchgear is a class of switchgear, which uses a special gas, superior dielectric gas (SF6), as the main insulation material. The SF6 insulates circuit breaker interrupters, switches, high voltage conductors, current transformers and voltage transformers.

    Jan 01, 2015SF6 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.
