Abstract
This paper discusses the impact of saturation of the current transformer(CT) on the current protection,differential protection and distance protection.The methods to prevent saturation,such as restrict the short-circuit current,choose the right current transformer,reduce the repeated burden of the current transformer are also discussed.
