摘　　要：研制了一种基于ARM的嵌入式电压互感器极性检测判别系统。系统通过对电压互感器二次侧脉冲电压占空比进行检测,判定电压互感器二次侧极性。辨别系统相比于传统的直流、交流检测方法能够智能、方便、正确地检测出极性。An ARM-based embedded identification system was developed.The system can identify the duty ratio of the pulse voltage on the secondary side of the voltage transformer.In this way,the polarity of the secondary side of the voltage transformer can be detected.The system includes two modules：data acquisition module and data identification module.Compared to the traditional DC/AC detection methods,it is able to detect the polarity more intelligently and conveniently.
