摘　　要：研究了基于法拉第磁光效应原理的光学电流互感器现场运行的条件和方法,给出了一套以光学电流互感器为核心的数字计量系统。通过长期与传统电流互感器并行运行的现场试验,对光学电流互感器的长期运行稳定性问题进行了试验研究。试验证明,该系统综合误差1.013%,由光学互感器组成的数字电能计量系统运行稳定,电能计量准确,测得数据准确可靠,满足工程计量检定要求。The conditions and methods for on-site operation of optical current transducer （OCT） based on the principle of Faraday magneto-optical effect are researched, and a digital metering system in which OCT is taken as the core is proposed. Through long-term on-site tests in which OCT and traditional current transformer are operated in parallel, the experimental investigation on long-term operation stability of OCT is performed. Testing results show that the comprehensive error of the digital metering system composed of OCT is 1.013%; its operation is .stable and the metering of electric energy is accurate and the obtained data are accurate and reliable, thus the proposed digital metering system can meet the demand of measurement verification specified in Chineses National Standard SD 109-83 and GB/T16934-1997.
