Research on characteristics of a high precision current sensor

This As a common sensor, current sensor is widely used in power generation, automotive electronics, rail transit and power field. In this paper, we describes the principle and characteristics of the mainstream current sensor, and compares the advantages of the traditional current sensor (such as CT) and the new current sensor (such as fluxgate, hall, magnetoresistance, etc.). Then we tests the developed fluxgate current sensor sample on the basis of analyzing the demand for current sensor in the power field. Finally, we conducted a preliminary test on the performance of the sensor and discuss the optimization of the sensor.
