LS series Rogowski coilDetailed product description：

I. Overview
Rogowski coil, also known as current measurement coil or differential current sensor, is a circular coil uniformly wound around a non-magnetic material. The output signal is the derivative of current over time. By integrating the output voltage signal through a circuit, the input current can be accurately restored.

II Structure Introduction:
No ferromagnetic material, no hysteresis effect, almost zero phase error; No magnetic saturation phenomenon, therefore the measurement range can range from several amperes to several hundred kiloamperes of current; The structure is simple and there is no direct circuit connection between it and the measured current; The response bandwidth is 0.1Hz-1MHz. Compared with traditional transformers with iron cores, Rockwell coils have a wide measurement range, high accuracy, stability and reliability, response frequency bandwidth, as well as measurement and relay protection functions. They are small in size, light in weight, safe, and meet environmental requirements.
Based on the Rockwell coil, it has the characteristics of real-time current measurement, fast response speed, no saturation, and almost no phase error. Therefore, it can be applied to relay protection, thyristor rectification, variable frequency speed regulation, resistance welding and other occasions with severe signal distortion.
