Clean Air GIS current and voltage transformers for air-insulated GIS up to 420 kV
Clean Air GIS comprises built-in current transformers and inductive voltage transformers for GIS up to 420 kV. Insulation is clean air, and the devices are installed in both SF6 and SF6-free GIS.
- Voltage class
- up to 420 kV
- Primary current (CT)
- up to 6000 A
- Insulation
- clean air
- Accuracy classes
- all IEC and IEEE classes for metering and protection
Price, availability and lead time on request. We help with analogue selection, customs clearance and delivery.
Description
The primary current of the current transformers is up to 6000 A. All IEC and IEEE accuracy classes for metering and protection are available. The design is free of partial discharges and requires no maintenance. Clean-air insulation suits GIS where SF6 is abandoned completely.
