8774 - Trafag AG

Density Sensor for Sulfr hexafluoride 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.

insulating gas: No Leak Too Small | TD World

The Trafag gas monitors do not have any control function on the breakers to isolate sections of the GIS; instead, they only supply both a low and low-low alarm indication. The theoretical design limit of the GIS bus and breakers is that at zero SF 6 pressure, the components' insulation systems will withstand 1.0 per unit line-to-ground voltage. Throughout the design process, this fail-safe philosophy was employed when practical.

sf6 gas circuit breaker maintenance | TD Guardian Articles

sf 6 gas leakage - gaz sf6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.

This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class insulating gas dead tank breaker, two to three exposures per phase are required to provide adequate data. For this breaker size, Siemens can typically complete inspections on one to two breakers per day.
