The Modern Current Sensors of Synthetic Magnetic Resin Part 3 - Transmission Characteristics and Design of the Sensor Amplifier

Article Preview

Abstract:

The article presents the results of unpublished research on the new generation current sensors, designed on the basis of cold-cast magnetic materials. The development of current sensors with core cast focused primarily on the possibility of their application for the measurement of large currents and for the purpose of measuring the electricity and power electronics. The article presents the results of measurements of transmission characteristics of the prototype sensor, the sensing ampli­fier design and measurement results of the entire scanning unit.
