First Sulfr hexafluoride-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.Get price

sf6 gas Insulated Current Transformers – Trench Group

Sulfr hexafluoride Insulated Current Transformers. SF 6 insulated current transformer are used to convert high transmission line currents (up to 6000 A) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system.
