OSWELL will present at the INA PAACE Automechanika in Mexico and the FIEE in Brazil in July.

A Rogowski coil is an inductive component that consists of a coil of thin wire wound around a magnetic core in the axial direction. When current flows through the Rogowski coil, it creates a magnetic field in the core, thereby producing an inductance. The Rogowski coil is used in electronic circuits such as oscillators, filters, and amplifiers, and is typically used in high-frequency circuits. In industrial settings, it is widely used in wireless communications, high-frequency induction heating, and power switches.

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 OFLS Series Rogowski Coils, known for their flexible, high-bandwidth, and dynamic current measurement capabilities, are increasingly being integrated with Internet of Things (IoT) technology to enable remote monitoring, predictive maintenance, and intelligent energy management. By leveraging wireless communication, cloud computing, and edge analytics, these coils can transmit real-time current data to centralized systems, enhancing grid stability, industrial automation, and energy efficiency. This article explores how OFLS Rogowski Coils are being transformed into smart sensors through IoT integration, their applications in energy management and industrial automation, and the key technologies enabling this evolution.

The rapid growth of new energy vehicles (NEVs) has driven the development of high-power charging infrastructure, where precise current monitoring and control are critical for safety, efficiency, and grid stability. OFLS Series Rogowski Coils, known for their flexible measurement, wide bandwidth, and dynamic response, have emerged as a key technology in NEV charging systems.
