The coil output gives a low voltage signal, therefore there is no danger from open-circuited secondary. This makes Rogowski transducers extremely suitable for temporary measurements, for example in combination with portable analysers; Unlike traditional current transformer with magnetic core, the Rogowski coil is a non-intrusive transducer.

Induction Coil Sensors â the Review - SLIDELEGEND.COM

The output signal of the Rogowski coil depends on the number of turns per unit length n/l and the cross section area, A, of the coil. Correctly designed and manufactured Rogowski coil inserted in the magnetic field at fixed points A – B should give the same output signal independently on the shape of the coil between the points A and B.

Induction coil sensors—a review - IOPscience

The special kind of helical coil sensor uniformly wound on a relatively long non-magnetic circular or rectangular strip, usually flexible (figure 25), is commonly known as the Rogowski coil, after the description given by Rogowski and Steinhaus in 1912 . Sometimes this coil is called a Chattock coil (or Rogowski–Chattock potentiometer, RCP).
