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.
