摘要

电流互感器的主要目的是将高压电力系统中的一次电流转换为可由精密的机电或电子设备处理的单电平。电流互感器是电力系统保护的重要组成部分。因此，为了保证电流互感器的正确运行，电流互感器的尺寸和精度等级应与系统电流及相关负荷和有效暂态条件相适应。本文提出了基于KTD和X/R比值因子的CT分级概念，并利用交变暂态编程(ATP)软件对不同-2 CT负荷下的CT性能和不对称电流下的CT饱和度进行了分析。

Current Transformer Sizing & SaturationCalculation with Transient PerformanceAnalysis of CT Using ATP Software

The main purpose of a current transformer is to translate the primary current in a high voltage power system to single level that can be handled by delicate electromechanical or electronic device. Current transformers are the very important aspect of the power system protection. So for the correct CT operation the accuracy class of CT sizing&should be Adequate with the system current & related burden and effective transient condition. In this paper, it proposes advance CT sizing concept with KTD and X/R ratio factor with CT performance analysis at different -2 CT Burden and CT saturation analysis at Asymmetrical Current condition with the Alternating Transient Programming (ATP) software.
