CLEAN AIR CURRENT TRANSFORMER
420 KV / 6000 A
Current Transformers, utilizing Clean Air as insulation medium, provide accurate and reliable current transformation, (measurement), merging proven safety with eco-friendliness.
CHARACTERISTICS
- For voltage levels up to 420 kV
- Rated primary current up to 6000 A
- Clean air as insulation medium
BENEFITS
- It uses environmentally friendly air instead of mineral oil or SF6
- Explosion-proof design in accordance with IEC 61869-1 Class II verified in tests
- Clean air does not cause or spread fire under any circumstances
- No aging of the insulation gas
SUSTAINABILITY
Regenera™ is our holistic approach to protecting ecosystems, fostering environmental harmony and promoting a circular economy.
External insulation made of composite insulator (porcelain insulator available on request)
The outer part is made of aluminum or another corrosion-resistant material, e.g., stainless steel
Cores/windings are located at the top of the current transformer [head type]
Bar-type primary conductor allows higher short-circuit currents and prevents a large voltage drop across the primary winding
MAIN FEATURES
Clean Air Current Transformers ensure accurate and reliable current transformation eco-friendly, proven and safe.
Clean Air
Like the air we breathe, the insulation gas consists of 20 % oxygen and 80 % nitrogen— the most sustainable insulating material for high-voltage devices.
Environmental
The current transformer insulation has a global warming potential (GWP) and an ozone depletion potential (ODP) of 0 and ensures CO₂ savings of 88 % over its entire service life.
Proven design
The design is based on the reliable SF6 devices that have been in use for 50 years and of which over 100,000 have been in service.
Enhanced operational safety
Superior Internal arc behaviour, absolutely explosion-proof, in accordance with IEC 61869-1 Class II and proven in tests. The safest insulation technology on the market, as pure air neither triggers nor spreads fire.
High Current
The bar-type primary conductor is designed for high service short-circuit current and prevents high voltage drops in the primary winding.
Maintenance
Maintenance-free and therefore cost- and time-saving over a service life of more than 30 years.
Technical/finance Advantages
Clean Air is not subject to the F-Gas Regulation leaks do not have to be documented or reported. No specialized personnel are required and there are no additional costs for disposal.
