Rogowski Coil

A Rogowski Coil is a flexible, air-cored current sensor used to measure alternating current (AC). It operates on the principle of electromagnetic induction, producing a voltage proportional to the rate of change of current. Known for its wide frequency range, non-intrusive installation, and high accuracy, it is ideal for measuring large or transient currents. Rogowski coils are widely used in power quality monitoring, fault detection, transient analysis, industrial automation, and smart grid applications, especially where space constraints or high-current measurement make traditional current transformers impractical.
