Dynamic characteristics of contactless wide range high current ferromagnetic converters for monitoring and control systems

The article substantiates the need for the use for the needs of industry and metallurgy, hydro-construction, land reclamation, irrigation and, in general, agriculture and water management, contactless conversion and measurement of large direct currents using non-destructive induction wide-range high-current converters of monitoring and control systems -magnetomodulation contactless ferromagnetic converters of increased sensitivity, the results of their constructive development are presented. It is shown that the developed converter, in contrast to the known ones, has increased accuracy and sensitivity, technological design and small weight and dimensions with low material consumption and cost. Its dynamics of work is investigated. The dynamic characteristics of magnetic modulation contactless ferromagnetic converters are considered. The results of their research are presented. It is shown that their transient time is 0.025 of the power frequency period. Therefore, they can be considered practically inertial free. The developed converter can be widely used in electrical systems in hydro-construction, land reclamation and irrigation, in water supply, industry, in railway transport, in science, technology and for checking electric meters at their installation site for contactless control of direct and also alternating currents.
