摘　　要：介绍了母线保护的基本原理,分析了电流互感器(current transformer,CT)饱和对母线保护的影响以及CT饱和的判别原理;在此基础上,通过分析目前国内外关于母线保护的研究现状和存在问题,提出了母线保护的研究思路和所面临的问题。This paper introduces the basic principles of busbar protection, and analyzes the influence of current transformer （CT）saturation on busbar protection along with the principle for discriminating CT saturation. By analyzing the present research state and existing problems of busbar protection at home and abroad, further work and possible challenges in this field are proposed.
