The Rogowski coil its an electrical device for measuring alternating and impulsive type of currents. The device consists of a conductor cable neatly wound in a helical shape on a flexible support, to form a coil (solenoid) of appropriate lenght.

The main advantage offered by a Rogowski coil compared to other measurement methods (curront transformers, Hall probe sensors...) consists of the flexibility and deformability of the probe, allowing it to be wrapped around a live conductor without disturbing it.

Since a Rogowski coil is not wound on an iron core, it has a low inductance which gives it a strong propensity to measure currents that vary over time even with high speed.
