“…These investigators also used the spinning current modulation technique and measured the current using a very small differential amplifier, which has a low offset of 350 μT and a high measurement frequency of 1 MHz. Blagojevic et al [123] reviewed the progress of Hall sensors with a Sentron CSA-1 and a built-in magnetic concentrator, which can measure AC and DC from tens of milliamps to hundreds of amperes. These proposed methods significantly reduce the production cost of Hall current sensors while increasing the measurement sensitivity and bandwidth.…”

The global energy industry is moving towards a trend of green and low-carbon transformation. A transparent power grid represents a new development form under this energy transition trend, integrating the power grid with new generation information and communication technologies, exemplified by the internet. The use of micro smart sensors allows real-time monitoring of many important parameters of power systems via current, which is crucial for ensuring safe, stable, intelligent, and green power grid operation. Here, based on the development logic of current sensing technology for traditional-smarttransparent power grids, we focus our research on high-current sensing in a transparent power grid. First, we review the widely used traditional current sensing methods of shunts and Rogowski coils. More advanced optical fiber current sensing methods and microelectromechanical system current sensing chips are then introduced, which are more suitable for the smart sensing requirements of transparent power grids. In addition, we present and discuss the technical characteristics, research status, application scope, advantages and disadvantages, and future development directions of the above methods in detail. Finally, we address many essential challenges including miniaturization, integration, low power consumption, passive wireless sensing, long-range operation, and complex environmental parameters in the comprehensive intelligent and transparent sensing of current parameters in power grids. To address these challenges, we present three possible development directions: sensor improvement, development of communication and networking technologies for sensors, and advancement of intelligent and fast processing methods through communication.

This paper presents a low-cost three-axis teslameter capable of measuring magnetic field intensity in industrial environments and high voltage facilities. It is based on an MFS-3A three-axis magnetic field sensor, and it can measure magnetic flux density up to ±5 mT in all three axes, with accuracy better than ±0.5% and excellent temperature stability. The proposed teslameter was calibrated using a state-of-the-art reference instrument, Helmholtz coil and temperature chamber. The paper describes the development and the calibration of the proposed teslameter. The obtained results are presented as well.

We review recent advances in magnetic sensors for DC/AC current transducers, especially novel AMR sensors and integrated fluxgates, and we make critical comparison of their properties. Most contactless electric current transducers use magnetic cores to concentrate the flux generated by the measured current and to shield the sensor against external magnetic fields. In order to achieve this, the magnetic core should be massive. We present coreless current transducers which are lightweight, linear and free of hysteresis and remanence. We also show how to suppress their weak point: crosstalk from external currents and magnetic fields.
