Information universal non-contact transducers of control and management systems

Abstract

In contact and communication devices, power equipment, relay protection and automation terminals, and in the electric power industry of smart cities and houses, microprocessor-based devices for relay protection and automation, distributed generation installations, including renewable energy sources, and energy storage devices, as well as “smart” ones, are beginning to be used automated information-measuring systems. They widely use non-contact transducers of direct and alternating currents of control and management systems. Their disadvantages are a narrow range of controlled currents, large dimensions and weight. Therefore, their elimination is important. The paper considers the general principles of building information non-contact transducers of large direct currents, the basic requirements for them. The paper shows the results of the development of one of the options proposed by us, universal non-contact magnetomodulating transducers of large direct currents with an extended range for various monitoring and control systems in the electric power industry of solar power plants, renewable energy sources, laser and solar installations, in industry, science and technology, in rural and water management, as well as in farming and in everyday life. The developed non-contact transducer can be widely used in industry, in agriculture, as well as in the electric power industry of smart cities.
