Tracer gas leak testing is a simple and highly-efficient method of leak detection that provides high sensitivity, accuracy, and repeatability. A tracer gas leak test can be used to test parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow testing, or to replace bubble test methods.

Alternative gases as SF 6 substitute Focus on the environment. SF 6 is an excellent quenching and insulating gas which has been used in the energy sector worldwide for more than 50 years. The energy related development in the high and extra high voltage range would have been impossible without the use of SF 6 with its excellent dielectric stability and good electric arc quenching properties.

The SF6-free equipment portfolio is now enlarged, with equipment covering the HV range from 145kV to 420kV. 15 utilities have decided to move forward and to install equipment with this alternative gas. GE has a number of projects on 18 sites that together will reduce the impact of the installed gas masses by more than 380,000 tons of CO 2

The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “ The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.
