为了解决电流互感器磁饱裕度的试验问题，对 JJG 1021《电力互感器检定规程》所推荐几种试验方法的可行性进行分析。分析结果表明负荷误差曲线外推法可在不影响国家计量检定系统表中 JJG 2082《工频电流比例计量器具检定系统框图》量值传递方式的基础上较好地解决电流互感器磁饱和裕度的试验问题。文章最后在分析测量结果不确定度的基础上提出了试验装置的关键技术参数，为电流互感器磁饱和裕度试验装置的研制提供理论依据。

To solve the test problem of current transformer magnetic saturation margin , the feasibility of methods in“power transformer verification procedures ” recommended by JJG 1021 has been analyzed.The analysis results show that the load error curve extrapolation method will well solve the current transformer magnetic saturation margin test problem without affecting the dissemination way of JJG 2082 “power frequency current ratio meter verification system diagram” in the national metrological verification system tables.Finally, the key technical parameters of testing device have been proposed through the analysis on encertainty of measuring results , which will provide theoretical foundation for development of current transformer magnetic saturation margin testing equipment .
