Study and Application of Giant Magnetoresistive Sensor

Introduction was made to the working principle, characteristics and present study situation of giant magnetoresistive sensor. This paper described some intelligent methods such that the giant magnetoresistive sensor was applied to measure bus bar current, and so on. The sensor is with small in dimensions, strong in anti-bad environment, high in sensitivity etc advantages, especially its static characteristics enabling it to be used as DC current transformer.
