ETCR-FB Flexible Coil Current Sensor

Product Characteristics

1. Measurement of AC current、 higher harmonic current、 complex waveforms current、 transient current、starting current、phase 、electric energy、power、power factor etc.

2. Current Range: AC 0A ~ 10000A ~ more(Optional)

3. Line Voltage:  Below AC 1000V

4. CT Structure: Rogowski coil

5. Coil Thickness : φ12mm

    No exposed metal conductors, non-contact measurement, safe and reliable. Small & light, soft and flexible, suitable for narrow environments and densely packed spaces, as well as measuring conductor currents with large or irregular shapes. Wide range, high precision, high reliability, and response frequency bandwidth. It is especially suitable for industrial environments with severe signal distortion such as relay protection, thyristor rectification, variable frequency speed regulation, semiconductor switch, power electronic conversion equipment, and arc welding.Current range: 0A ~ 10000A ~ more; Resolution: 10mA. The coil length and interface can be customized according to user requirements.
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.
