An SF6 gas analyser has been designed to test SF6 in electrical equipment without service disruption. It draws a sample of SF6 from the working equipment, analyses it in accordance with prescribed testing requirements, and pumps it back into the equipment.
The analyser helps to perform regular analysis as part of a condition maintenance schedule, ensuring that equipment and personnel are properly protected.
When partial arcing or a failure occurs within electrical equipment, this can cause the creation of decomposition products. Early identification of excess decomposition products will help to eliminate power outages and failures, alongside unnecessary inspections, which would cause unavoidable SF6 emissions.
