SF6 is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore it is commonly used within electrical switchgear, transformers and substations as an electrical insulation, arc quenching and cooling medium.
The crystal selected as an optical cell material provides high temperature stability of the electro-gyration constant and exhibits no piezoelectric effect, which gives the possibility to create a voltage sensor operating in wide temperature and frequency ranges; High measurement accuracy owing to Faraday effect compensation
Once the analysis has taken place, the user has the option to store the SF6 gas within the analyzer for disposal or recycling, or to pump it back into the electrical equipment at pressure, ensuring that no gas escapes in-between sampling.
