A Rogowski coil is an electrical device that is used for measuring alternating current (AC) and its corresponding electric fields. It consists of a coil of wire that is wound in a helix shape, with the turns of the coil placed closely together. The Rogowski coil is named after its inventor, Walter Rogowski, a German physicist who developed it in the early 20th century. The coil operates on the principle of electromagnetic induction. When an AC current passes through the center of the coil, it creates a changing magnetic field which induces an electric current in the coil. This current is proportional to the rate of change of the magnetic field, which in turn is proportional to the AC current being measured. One of the advantages of the Rogowski coil is that it does not require direct contact with the circuit being measured. This makes it useful for measuring high-voltage or high-power systems, where direct contact with the circuit may be dangerous or impractical. Another advantage is that the Rogowski coil has a relatively flat frequency response, which means it can accurately measure a wide range of frequencies. Rogowski coils are used in a variety of applications, including power grid monitoring, electrical testing and measurement, and research in fields such as plasma physics and fusion energy. They are also used in some medical imaging applications, such as magnetic resonance imaging (MRI).
