保护用电流互感器误差分析和应用

Error Analysis and Applications of Protective Current Transformer

论述了电流互感器10%误差曲线和误差的产生原因及现场应用励磁特性曲线进行10%误差曲线校核的方法。在现场继电保护整定中,具有一定实际意义。

Discussed 10% error curve of current transformer, causes of the error, and the method that using excitation curve in the field to check 10% error curve. And it had some practical significance in on-site relay protection adjustment.
