<p>This article presents the results of modeling and experimental investigation of three-phase electromagnetic current converters equipped with sensitive elements, applied in asynchronous motors. The aim of the study is to <br /> evaluate the stray magnetic field and output signal characteristics to enhance the monitoring efficiency of reactive power. Different connection schemes (series, parallel, and differential) of the converters are examined, and their static and dynamic characteristics are obtained. The models were built using Matlab, and experimental measurements were carried out with the CassyLAB device. The study analyzes the steady-state time, harmonic distortion levels, and output signal amplitude. The results demonstrate that differential connection of sensitive <br /> elements provides the most effective performance. This approach may be employed to improve energy efficiency and develop monitoring systems in industrial electric drives.</p>
