Abstract: A method was presented to eliminate the effect of magnetic crosstalk on the current measurement by adjusting the position and angle of the optical current sensor.The quantitative relationship between the magnetic crosstalk and the distance between the two conductors and the distance and the angle between the sensor head and the main conductor is analyzed theoretically, and the optimal position of the sensor was determined.The experimental results show that the influence of the magnetic crosstalk of adjacent conductors can be minimized by adjusting the sensor's position, and the measurement precision of the optical current sensor is improved.
