Current sensors with Rogowski coils are very lightweight, quickly mounted without breaking the circuit with the measured current and are capable of measuring high currents - tens and hundreds of kiloamps. In addition, they are characterized by a high linearity of frequency dependence, which makes it possible to measure currents with a high harmonic content. There is an opinion about the high error of the Rogowski coils with inaccurate alignment of the conductor with the measured current. Algodue's flexible clamps MFC150 disprove it. Watch the video.
