Quantitative electrical switchgear leak rate

Quantitative electrical switchgear leak rate

Advanced Energy's Innova® 3731 SF6 system utilizes the ultra-sensitive photoacoustic sensing technique to provide a leak detection solution that monitors large switchgear rooms. The system verifies that GIS equipment operates below the 0.5% yearly leakage rate, which is the industrial target. And the 3731 system quickly detects any excessive increase in the leak rate.
