Notes
- Note
- Rogowski technology allows the coils to measure a wide primary current range of up to 10,000 A without loss of accuracy, because there are no saturation effects. The requirements for standards EN 61869-1, EN 61869-2, EN 61869-6 and EN 61869-10 are only partially met, as there are fundamental differences with current transformers for a Rogowski coil.
Test Voltage
- Voltage for isolation test
- AC 7.4 kV; 50 Hz; 1 min
