- Fully type-tested meeting all lEC and IEEE metering and protection classes
BENEEFITS
- Partial discharge-free design and process
- Modular design eliminates the need for a wide range of components.
- Maintenance-free during a long lifetime of more than 30 years
MAIN FEATURES
A Legacy of durability
Design
The explosion-proof design is based on the combination of a compressible insulating medium and the rupture disc.
Mechanical characteristics
Variable due to freely selectable installation position, wide range ferroresonance-free design without the use of external damping and excellent seismic behavior – depending on the GIS structure.
Internal insulation device, IID
When testing GIS switchgear, the VT needs to be disconnected to prevent saturation. IID is part of the VT design and while the IID can only operate at no load and no current, it is designed to isolate the VT from the GIS.
Response
Optimized high-voltage coil ensures consistent electrical stresses under both, transient and steady state conditions.
