In today's increasingly digital world, the need for accurate and reliable current measurement has become paramount. Current sensors play a vital role in various electronic applications, providing insights into power consumption, energy efficiency, and system performance. In this blog post, we will delve into the significance of current sensors, their working principles, and explore their widespread use in different fields.

Split-core iron core current transformers are electrical devices used to measure high voltage currents. They can convert high currents into low current outputs and ensure that the current information is not lost during output. This type of transformer consists of an iron core and several coils, with the iron core able to induce current onto the coils which is then stepped down through the circuit.

A rogowski coil is a circular coil evenly wound around a non-ferromagnetic material. The output signal is the derivative of the current with respect to time. Through a circuit integrating the output voltage signal, the input current can be truly restored. The coil has the characteristics of real-time current measurement, fast response speed, no saturation, suitable for AC, especially high frequency current measurement.

​The ring indicates the number of primary and secondary windings of the voltage transformer. One primary winding is removed, and the rest are all secondary windings.

Features ● Output standard DC voltage ● Power-taking CT open-close structure, easy to install and operate ● The power conversion device is fixed with screws, which is easy to install ● Reserved for external energy storage device port
