The article presents the results of research on inductive current transducers in the form of a uniform winding non-magnetic ring with a rigid and flexible construction encompassing the flow of processed current in the frequency range of up to 150 kHz. The research results for the developed transducer were related to the results obtained in simulations conducted on the transducer simplified model. The frequen-cy tests of this type of transducers are of key significance in the assessment of the applicability of a giv-en transducer in the measurements of network signals with high-order harmonics, and particularly the assessment of the construction capacity of inductive current transducers in the form of the Rogowski coil.
