Product Characteristics
3. Line Voltage: Below AC 1000V
4. CT Structure: Rogowski coil
5. Coil Thickness : φ12mm
Function |
Measurement of AC leakage current、 large current、higher harmonic current、 complex waveforms current、 transient current、phase、electric energy、power、power factor etc. |
Detection Method |
Flexible coil CT: The output signal is the differential of current to time. By integrating the output voltage signal, the input current can be truly restored. |
