SF6-filled leak detection for Transformers

LumaSense SF6 Leak Detector is able to measure the total concentration of the Sulfur Hexafluoride gas in a monitored enclosure where the switchgear (or other SF6-filled equipment) is tested. It is critical to detect leaks and improve "gas-tightness" during the testing period to ensure the equipment will perform in the field.
