insulating gas circuit breaker maintenance | TD Guardian Articles

The first generation of gaz sf6 circuit breakers was the lower voltage classes of 72kV and 145kV. As Sulfr hexafluoride breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing sf 6 as the line-to ground dielectric insulation.

Digital radiography for inspection of sf 6 | TD Guardian

This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class sf6 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.
