Abstract
A current transformer saturation identification method of transmission line based on current sample data is proposed in this paper. Mechanism and characteristics of current transformer saturation are analyzed firstly. Current transformer saturation identification plane is proposed. It is divided into three parts: internal fault zone, external fault zone and current transformer saturation zone caused by external faults. For current transformer saturation caused by external faults, current differential protection is blocked. The RTDS simulation results show that the method can identify CT Saturation quickly and sensitively. It is not impacted by data window length.
