Abstract

The magnetic characteristics of nano-crystalline alloy MN-11 tape-wound magnetic core are studied and a mathematical model of the current transformer with such magnetic core is made in the form of block diagram of the servo system. Designed and manufactured current sensor for digital control systems in the form of high-precision current transformer with a specified minimum value of the rated instrument security factor of the secondary winding. Experimentally confirmed the high level of metrological performances of the sensor and their practical stability in the frequency range 50-2000 Hz.

Keywords: nano-crystalline alloy, the sensor, the mathematical model, the error
