摘　　要：介绍了巨磁电阻效应的发现、发展和应用情况,在自制实验平台上,分别测试了深圳华夏公司和美国NVE公司传感器的静、动态特性。结果表明,NVE传感器在线性区间、静态灵敏度、线性度、磁滞等方面优于华夏产品。在测试结果的基础上,对NVE公司巨磁电阻传感器的应用前景进行了探讨,给出了该传感器应用于电力系统母线大电流测试时的具体方案,并对方案实现过程中可能遇到的问题进行分析。The discovery, development and application of giant magneto-resistance sensor were introduced. The static and dynamic characteristics of two sensors of different corporation were in- vestigated in self-designed testing equipment. The testing results show that the performance of NVE product is superior to that of Huaxia products. The application prospect of NVE product was discussed, and a new design method to measure bus current was presented.
