摘　　要：概述了超、特高压电力系统中适用暂态保护用电子式电流互感器的必要性,介绍了TPE级电子式电流互感器及试验条件,给出了电子式电流互感器的暂态试验方法及试验系统,该试验系统已对多套110～800kV电子式互感器进行了暂态误差测试,满足国标及IEC标准对暂态误差试验的要求,通过和现有的电流互感器暂态误差测试系统比较,其最大峰值瞬时误差的差值小于0.5%。In this paper, the necessity of using electronic current transformer for transient protection in UHV power system is discussed. The electronic current transformer with the accuracy class of TPE and its test conditions are introduced. The test system and test method of instantaneous error of electronic current transformer are presented and used to test several 110~800 kV electronic current transformers, and the results meet the international and the IEC standards for instantaneous error test. Compared with the existing test system, the difference between the maximum peak instantaneous errors is less than 0.5%.
