В данной статье изложены результаты моделирования и экспериментальных исследований трёхфазных электромагнитных токопрeобразователей, используемых в асинхронных двигателях и основанных на применении чувствительных элементов. Основная цель исследования заключается в повышении эффективности контроля реактивной мощности путём оценки распределения магнитного поля 
в роторной части двигателя и анализа характеристик выходного сигнала. Рассмотрено влияние последовательного, параллельного и дифференциального включения электромагнитных токопрeобразователей на выходное напряжение, определены их статические и динамические  характеристики. Модели разработаны в программной среде Matlab, а экспериментальные исследования проведены с использованием устройства CassyLAB. Проанализированы синусоидальность выходного напряжения, время достижения установившегося режима и уровень гармонических искажений. На основе полученных результатов установлено, что токопрeобразователи с дифференциальным подключением чувствительных элементов обеспечивают наибольшую эффективность. Представленный подход имеет практическое значение при создании систем контроля качества энергии в асинхронных двигателях.

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 
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 
elements provides the most effective performance. This approach may be employed to improve energy efficiency and develop monitoring systems in industrial electric drives.
