Rogowski coils (see Sidebar and References 1 and 2 at end) perform passive current measurement and are used in test and measurement devices and power-monitoring activities. Calibration is required to ...

Swiss sensor maker LEM has developed a novel non-contact current measuring technique based on a differential adaptation of the Rogowski principle. Rogowski coils Invented in 1912, Rogowski coils are ...

The CTRC Rogowski coil current transformers are flexible, rope-like current sensors that can be connected around conductors. With their flexible design, the CTRC transformers are perfect for large bus ...

One of the joys of writing for Hackaday comes in learning new things which even after a long engineering background haven’t yet come your way. So it is with the Rogowski coil, an AC current sensing ...

When developing the new Rogowski coils, LEM decided to offer a simple and generic product, keeping in mind that the integrator technology leads to the best performances and is a well known method.
