摘要
本文介绍电流互感器基本原理及其产生误差的两方面因素,给出二次负载的计算方法,并结合现场实际电流二次回路通流试验对二次负载进行分析和计算,阐述二次负荷对电流互感器运行工况的影响,本文对实际现场二次回路故障检查处理很有借鉴意义。
This article described the basic principles of the current transformer and the two factors causing error. The influence of secondary load to current transformer was expounded applying the calculation and analysis of secondary circuit current testing in the actual site. The paper had much reference to fault checking in actual work site
