- World leader in seismic solutions
- Expertise in 800 kV
- Stable accuracy over its lifetime
- Maintenance free
- Design verified by extensive field experience
- Protection against bursting
Characteristics
- 72.5 to 800 kV
- Up to 6,000 A
- In short-circuit: up to 120 kA1” (Isc dyn: 324 - kA peak)
- Secondary cores: up to 8
- Oil expansion by stainless-steel bellows
- Oil level indicator
- Available high and extended range accuracy design (ERCT)
- Compliance with IEC and IEEE or equivalent standards
- DC current transformers available
