摘　　要：在现代智能电网的智能化变电站中,电子式电流互感器逐渐取代传统的电磁式电流互感器,得到越来越广泛的应用。暂态特性是保护用电流互感器的重要性能,文中针对不同原理的电流互感器的暂态特性进行了相关的试验研究。首先概述了电磁式电流互感器的暂态保护TPY级和电子式电流互感器暂态保护TPE级的定义及试验要求,然后通过实际的试验,对不同原理的多台电流互感器的暂态特性进行比对,得到多组比对试验数据。试验结果表明:电子式和传统电磁式的电流互感器都能达到标准要求的暂态性能指标,对用户的选型及生产厂家的设计均有指导意义。In the modem smart grid intelligent substation, the electronic current transformers gradually replace the traditional electromagnetic current transformers and get more and more widely used. Transient characteristics are important for the protection of current transformers. In this paper, the transient characteristics of current transformers with different principles are studied by actually test. Firstly, the definition of TPY class for electromagnetic current transformer and TPE class for electronic current transformer are overviewed, and then the transient characteristics of multiple current transformers with different principles are compared though actually test. The test results show that the electronic current transformers and the traditional electromagnetic current transformers all can meet the standard requirements of transient performance indicators. This discussion may be useful to manufacturers and users.
