摘要
电流互感器饱和问题会增加母线差动保护误动作的可能性,这个问题必须引起高度重视,本文结合母线保护的实践经验和生产中对母线保护的特殊情况,介绍如何分析和处理,为电力生产现场工作人员提供一些借鉴和帮助。
The problem for saturation of current transformers will increase the chance of malfunction of busbar differential protection. And we have to takes this issue very seriously. This paper combined the practical experience and the special conditions of busbar protection to introduce how to analysis and a process this issue. With what have been done in this paper can provide a reference and giving a help for people of power system.
