Current transformer in power system is mainly used for current measurement,electric energy metering and,in cooperation with the relay,for protection of over current and over load of system and equipment. In this paper,the design method of current transformer with special small transformation ratio is proposed,which can meet the performance requirements of current transformer with small transformation ratio. Moreover,the design examples meeting China National Standards and projects requirements is given.
