Digital radiography for inspection of sf6 gas | TD Guardian

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

insulating gas circuit breaker maintenance | TD Guardian Articles

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

Essentials of insulating gas monitoring | TD Guardian Articles

Because gaz sf6 has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world’s usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.

Siemens to provide UK’s first sf6 gas free 145kV vacuum circuit

It is the first time that clean air has been used instead of Sulfr hexafluoride to insulate 145kV circuit breakers in the UK. It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to Sulfr hexafluoride which has traditionally been the method of insulation in high voltage switchgear since the 1960s.
