  • SF Maintenance Equipment Fundamentals

    sensor used in a hygrometer should be capable of handling arced SF 6 and should not require that the gas be pre-filtered. It is extremely important to exclude moisture from any system employing SF 6 as a dielectric. Moisture can react with SF 6 under the influence of electrical discharges to form toxic and corrosive compounds.
