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

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The article presents the results of unpublished research on the new generation current sensors, designed on the basis of cold-cast magnetic materials.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.

A Current Compensated Transformer for Measurement of Large AC Currents in Power Networks

“…Based resin developed its own magnetic workers Electro Technical Laboratory of the Department of Technical Subjects Faculty of Education University of Hradec Kralove special toroidal sensor for measuring large AC currents in order of frequency of 100 kHz [1][2][3]. Using the knowledge gained during the development and construction of transformer compensators for interference voltage DC power sources [4,5] for measuring large AC currents of current-compensated transformer is designed with direct measurement of the current passing through without any negative impact on his return waveform.…”
