Abstract

This paper presents the application of a compact and fully integrated LED quantum sensor based on the NV centers in diamond for current measurement in a busbar. The magnetic field measurements from the sensor are directly compared with measurements from a numerical simulation, eliminating the need for calibration. The sensor setup achieves an accuracy of 0.28% in the measurement range of 0-30 <inline-formula><math xmlns=“http://www.w3.org/1998/Math/MathML” display=“inline”><semantics><mi mathvariant=“normal”>A</mi></semantics></math></inline-formula> DC. The integration of advanced quantum sensing technology with practical current measurement demonstrates the potential of this sensor for applications in electrical and distribution networks.
