摘要
阐述了电流互感器在主变中各绕组极性的接法，研究了电流互感器在线路保护中各绕组极性的接法其结论可供工程技术人员在事故分析时参考，或在建设变电站中作为电流互感器接线的借鉴．
The current transformer in the main variable with each winding polarity connection method is described, different substation grounding methods in the different uses of the polarity are studied. This conclusion can provide reference for engineers in the accident analysis, or as a current transformer connected line reference in the construction of substation.
