| 摘 要： | 用光学电流互感器(OCT-OpticalCurrentTransducer)替代传统的电磁式电流互感器(CT)是电力系统电流测量的发展趋势。介绍光学电流互感器普遍采用的Faraday磁光效应原理、各种OCT的性能特点和典型应用情况。指出闭合式块状材料型OCT具有较好的实用前景，而全光纤式OCT则是最终的发展趋势，在某些特殊应用领域，OCT已达到实用化要求。

| Abstract: | The optical current transducers will take place of the conventional current transformers to be employed in the current measurement of the electric power system in the future. In this paper, Faraday effects principle and the characteristics and application of OCTs are introduced. Although the circular bulk-glass OCT has its good application at present, the all-fiber OCT is expected to be the best approach in the future. |
