Rogowski coil, also known as flexible current transformer, is an ideal electrical device used for real-time measurement of alternating current in power grid based on the principle of electromagnetic induction. The current transformer adopts True RMS measurement and linear temperature compensation technology to provide accurate AC current measurement and convert it into a standard DC output signal that is proportional to the input current, providing DC24V safe voltage. The flexible current transformer features high accuracy, high-degree galvanic isolation, high safety and low power consumption, which is widely applied in a variety of fields such as metallurgy, electroplating, welding, etc.
