Detecting and Quantifying Sulfur Hexafluoride (SF6) Leakages in the T&D and Power Industry
The SF6 Leak Detection products from LumaSense offer a combination of performance and convenience. Based on the company’s Photoacoustic Spectroscopy (PAS) technology, 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.
- The SF6 leak detection system – INNOVA 3731 – features ultra-high sensitivity with its state-of-the-art photoacoustic monitor. It draws air samples from up to 24 locations for maximum coverage of the GIS substation. Tubing lines can easily run into existing control cable trays, or trenches. Analog and alarm relay outputs can be connected to local RTU, says the company in a statement.
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.
The 3731 system verifies that the GIS Equipment operates below the industrial target of 0.5 percent yearly leakage rate or better.
