抄録(英) | A single solid-state magnetic sensor can be used to measure a current by sensing the field near the conductor in a non-contact way In order to improve the accuracy of the measuring system, magnetic sensor arrays have been introduced in the current measurement around the conductor An analytical algorithm based on Discrete Fourier Transform (DFT) is presented in this paper, which can separate the effects of the field generated by the current under measurement from the interference fields A general mathematical model of the interference analysis is set up, which can be used for both DC and AC current measurement and has no restriction on the shape and number of the current conductors Numerical simulations associated with preliminary experimental results confirm the validity of the approach |
