AI Technical Summary
Existing current measurement technologies have insufficient calculation accuracy and high computational complexity on complex-shaped conductors. Traditional methods are bulky, slow to respond, and have poor accuracy, making them difficult to adapt to the complex power environment requirements of smart grids.
By dividing the cross-sectional shape of the current-carrying conductor into multiple graphics, calculating the spatial magnetic field of each graphic cross-section, and determining the spatial magnetic field of the target current-carrying conductor based on these magnetic fields, the numerical integration method is used to process the magnetic field distribution of complex-shaped conductors.
It achieves efficient and accurate calculation of the magnetic field distribution of complex-shaped conductors under different conditions, reduces the volume of the current measurement device, simplifies the installation design, avoids core saturation and DC bias problems, and provides stable and accurate magnetic field measurement results.
