Effect of CT transient characteristics on transfer of inrush

Effect of CT transient characteristics on transfer of inrush

During the inrush period, multiple misoperation accidents of differential protection of transformers happened, which seriously threatened the safe and stable operation of power grid. In the traditional malfunction analysis, only the inrush current process is considered, and the electromagnetic trans...
