The Simulation Technology Research of Hall Current Sensor

Hall current sensor is a new generation industrial sensors which was widely used in electrical measurement. After introducing the current measurement by hall sensor, the 3D model of current-carrying conductor was built by ANSYS, and the effect caused by current-carrying conductor’s shape and the position of hall sensor was analyzed. Along with the effect of electromagnetic field of adjacent phase current-carrying conductor, the ferromagnetic shield was proposed to reduce this effect and improve the measurement accuracy. The theoretical analysis is verified by the simulation results, which can do a lot in improving the product.
