Product Description

Product Description

Introduction to Rogowski coil

The Rogowski coil also called a differential current sensor, is an "empty core" toroidal coil arranged around a conductor, so that the alternating magnetic field generated by the current induces a voltage in the coil. The coil is actually a current transformer coupled to the conductor under test, and the voltage output directly from the coil is proportional to the rate of change of the current.

For example:@50Hz/1kA Vout=85mV, @60Hz/1kA Vout=85*60/50=102mV.

If you want to obtain the current waveform or frequency independent current value, you need to add an integral circuit to achieve 90° phase shift compensation and frequency equalization.

The RFIZ series is a flexible current transformer based on the Rogowski coil principle, which is a flexible rod-like hollow core coil that can be connected around the wire when it is "live". They are easier to install and measure than traditional open and closed CT.

Due to its flexible design and light weight, it is ideal for use in busbars and irregular shaped multi-core bundles. Rogowski coil technology has low phase shift error, inductance and good linearity, but is basically unaffected by electromagnetic interference and pulsed DC current, so it has high accuracy.

The RFIZ-AC series coils can be used for both single-phase and three-phase measurement applications.

Built-in voltage integrator can simplify wiring installation, can output 0~2V AC voltage, rated input can be selected between 30A~10kA

Dimensions and Diagram

Notice:

1. According to the rogowski coil principle, output voltage is proportional to the derivative of the input current (di/dt).

2. The output voltage is a constant rated frequency sinusoidal waveform in Hz, measured by the RMS value.

3.Vout (RMS)=Amps(RMS)×Hertz×K×10. the K depends on the manufacturer, for 50mV model the K value is 1.7.

Warning:

Do not apply pressure to the coil by any form of mechanical force (e.g., twisting, piercing, excessive pressure, excessive bending, etc.), which will reduces the accuracy of the device greatly
