Rogovski coils

Rogowski coils are special measuring devices for measuring alternating currents. They consist of a flexible, non-magnetic coil that is wound around a conductor. When an alternating current flows through the conductor, it generates a changing magnetic field that induces a voltage in the Rogowski coil. This induced voltage is proportional to the current flowing through the conductor.

A major advantage of Rogowski coils is that they do not require a direct electrical connection to the circuit, which makes them safe and easy to use. They are particularly suitable for measuring high currents or for applications where galvanic isolation is required. Rogowski coils are often used in energy monitoring, industrial automation and research to perform accurate and reliable current measurements.
