  • SF6 circuit breaker maintenance | TD Guardian Articles

    The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using SF6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV.

  • First SF6-free voltage transformers for 420 kV | References

    The insulation medium of the blue instrument transformers has no impact on the environment, therefore the Global Warming Potential is zero. SF 6 or other fluorinated gases, called F-Gases, are replaced by applying dry synthetic air, so called „clean air“, as an insulation medium for gas-insulated equipment. Clean air consists of 80% nitrogen and 20% oxygen, natural elements in the surrounding atmosphere.
