The 4 Types of Moisture Sensors Used for gaz sf6 Gas

These sensors work very well within the expected moisture range of most outdoor gaz sf6 circuit breakers, but can be inaccurate at times when measuring very dry sf6 gas (typically below 50 ppmv). Because the sensor is exposed to ambient moisture when in storage, it needs to be dried with new sf 6 gas before using it (a process referred to as “dry-up testing”).

Moisture Measurement, Moisture Control in gaz sf6 Gas Switchgear

What is the dew point of an sf 6 system having a moisture content of 300 PPMV at guage pressure 152 kPa (22psig) Pressure = 300 * 10 -4 (22 + 14.7) 51.7 = 0.57mmHg. The 51.7 multiplier is used to convert the pressure from psia to mmHg for use with Table :1 (760 mmHg = 14.7 psi, so 1 psi = 760/14.7 = 51.7 mmHg)

The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing insulating gas as the line-to ground dielectric insulation.
