8774 - Trafag AG

Density Sensor for sf 6 and other gases The Trafag gas density sensor type 8774 was specifically designed for monitoring insulation gases. The gas density is measured with an oscillating quartz with excellent long term stability. The constant resonant frequency of a quartz oscillator under vacuum is compared with the resonant frequency of an identical quartz situated in the sample gas.

Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

At the time of production, Sulfr hexafluoride gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required. The insulating material used in the manufacture of modern Sulfr hexafluoride gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.
