摘　　要：阐述了网损测量中存在误差的现象,分析电流互感器运行于非线性区间是造成该现象的原因,制定了电流互感器满足准确级的一次电流阈值检测方法,分析影响该阈值的因素,对未来电流互感器的发展方向提出建议。This paper elaborates and analyzes the phenomenon of power loss measurement error,and concludes that the error is caused by current transformers running within non-linear range.Therefore,the threshold detection method is formulated for current transformer to guarantee accuracy-class primary current,and the factors influencing threshold is analyzed.Finally,some suggestions are proposed for the development of current transformers.
