摘　　要：在数字式测量仪表条件下,供电系统中电磁式电流互感器的二次侧负荷明显降低,但电磁式电流互感器的设计制造标准至今未变,其中的额定容量比现在的实际负荷要大很多。本文讨论二次侧负荷对电磁式电流互感器设计参数的影响,发现二次负荷降低后若能相应减小电流互感器的设计容量等参数,能显著降低原材料的消耗量及制造成本;文章进而提出了降低电磁式电流互感器设计容量的现实意义和价值。Under the condition of widespread adoption of digital of electromagnetic current transformers （ECTs）are decreased manufacture standard of the ECTs has not been changed so far. practical loads. This paper discusses the influence of decreased figures out the decrease of manufacturing raw materials and cost forward the significance of reducing the capacity of the ECTs. measuring instruments, the secondary winding loads significantly in power system,but the design and Of which the rated capacity is much more than the secondary winding loads on designing of the ECTs, after the change of design parameter, and then puts
