High-current contactless ferromagnetic converters for multi-profile monitoring and control systems

The article shows that the undesirability of breaking current circuit for temporary inclusion electrical measuring devices, presence large power losses on shunts, impossibility under conditions technological process, as well safety requirements caused contactless conversion and measurement DC currents in circuits without them metallurgy, electrochemical industry, railway transport, laser technology, renewable energy sources, land reclamation, irrigation general agriculture. Lightweight detachable wide-band stationary portable non-destructive converters meters direct are not yet mass-produced worldwide. Therefore, it is very important to develop study currents, having an extended range converted with small dimensions weight increased accuracy sensitivity, a simplified technologically advanced design low material consumption cost, ability convert both constant variable high fixed sensitivity control. All these met by effective multifunctional magneto-modulating developed us. results development one given work. issues its dynamics considered. his research shown. It was found transition time him 0.025 period industrial frequency. can be considered practically inertia-free. converter widely used monitoring control systems water supply, irrigation, science, technology alternating checking electric at place their installation.
