套管式电流互感器在二次设计中的合理选择

Reasonable Choose to Bushing Current Transformer in Secondary Design Circuit

针对套管式电流互感器铁芯易饱和,引起测量误差增大及保护装置误动或拒动,提出了测量用电流互感器和保护用电流互感器的不同选择方法在设计中的应用。

It aims at measure the error increase and protection fixed unnecessary operation and ineffective opration because of core saturation provide the different choice way of application to measure current transformer and protection current transformer.
