摘要
针对电流互感器接线错误及二次阻抗过大的问题进行了分析,探讨了电流互感器参数间的关系以及电流互感器两组极性接反所造成的对二次回路电流、二次负荷阻抗和继电保护可靠性的影响。
In view of occasional erroneous wiring of current transformers and secondary impedance of ten met with in the power industry, the paper discusses the mutual influence among different parameters of current transformers, as well as the effect of erro- neous wiring of transformer terminals on the sec- ondary loop current, on secondary load impedance and the reliability of protection by relays.
