摘　　要：对一种新型的敏感机理-巨磁电阻效应进行研究与分析,介绍了巨磁电阻效应的基本原理,对基于巨磁电阻效应的几种传感器性能进行了测试,在全面对比分析多种巨磁电阻传感器的测试结果后,对巨磁电阻传感器在电力系统交/直流测量中可能的应用前景进行了分析与展望。Electronic transformer taking place of electromagnetic transformer is the intending trend, and the research of its sensing unit is the key to put into practice. In this paper, a new sensing principle, giant magneto-resistance effect was studied. Its basic principle was simply introduced at first, and then its characteristics was tested and analyzed. Based on the testing results of different GMR sensors, the possible application of GMR sensor in AC/DC current measurement of power system was discussed at last.
