摘要
介绍了电力系统发生故障时暂态过程对电流互感器的影响,在对电流互感器TPY级铁心暂态性能数学分析的基础之上,通过实例利用计算机软件对TPY级铁心各设计参数对其暂态性能的影响做了分析,最后对电流互感器TPY级铁心暂态性能作了一定的总结。
This paper introduces the influence of transient process of fault occurred in the electric power system on current transformer and, based on the mathematical analysis of transient perform. ance of current transformer＇ s TPY core and with the help of computer software, the influence of each design parameter on the transient characteristics of TPY core is analyzed through actual exampie. Finally the transient performance of current transformer＇s TPY core is summarized.
