| Abstract: | The operating faults in the power system often lead to CT steady and transient saturation, which have different effect and demand on relay protection device. Through introducing saturation characteristics of CT under two kinds of different work situation, lists the CT example of boost station in Ningxia Datang International Daba Power Generation Co.,Ltd. to calculate and explain, analyzes the different characteristic and significance in real work of the two types of CT. |
