The SF6 Leak Detection products from LumaSense offer an unmatched combination of performance and convenience. Based on the company’s Photoacoustic Spectroscopy (PAS) technology, they offer highly accurate, repeatable, and reliable quantitative gas analysis and detection. The growing environmental requirements and pressures regarding the use of SF6 make LumaSense’s leak monitors a coveted tool designed for routine testing or continuous monitoring at minimal costs.","New regulatory frames, like the F-Gas Directive (EC 517\/2014), are mandating the use of leak detection systems in the vast majority of high-voltage SF6-GIS installation in order to better mitigate the risk of SF6 emissions in particular when the existing gas instrumentation is not accurate enough to provide early detection: Pressure\/density switches used for safety considerations (to prevent catastrophic failure) lack of sensitivity, and manual leak checks only provide discrete check points. Instead, stationary leak detection systems enable a permanent monitoring and early warning in the case of a leakage event occurring.","Our 3731 system leverages 20-years of leadership on the ultra-sensitive photoacoustic sensing technique to provide a direct and integral leak detection solution capable of monitoring large switchgear rooms. The system verifies that the GIS Equipment operates below the industrial target of 0.5% yearly leakage rate or better.","The 3731 system can detect within a short response time any excessive increase in the leak rate, enabling to decrease the number – hence the cost – of periodic leak checks while providing early leak detection.
