SF6 Breakers sensor module nantong

Measuring instruments are used to monitor ambient air, trace leaks and to measure the SF6 quality of electrical operating equipment. The SF6 gas must always be pure since humidity and toxic or corrosive decomposition products in circuit breakers impair the insulating properties of the gas.

  • SF6 circuit breaker maintenance | TD Guardian Articles |

    The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.

  • The 4 Types of Moisture Sensors Used for SF6 Gas

    These sensors work very well within the expected moisture range of most outdoor SF6 circuit breakers, but can be inaccurate at times when measuring very dry SF6 (typically below 50 ppmv). Because the sensor is exposed to ambient moisture when in storage, it needs to be dried with new SF6 gas before using it (a process
