The utility model discloses a current transformer DC magnetic bias error characteristic measuring device. According to the equal ampere-turn principle, primary simulated current can be respectively a power frequency current source and an independent DC current source, which are independent from each oter, and a standard CT can be used to detect the change of the error characteristics of the measured CT after being influenced by the DC magnetic bias. The measuring device comprises a current comparison type error characteristic measuring device or a voltage comparison type error characteristic measuring device. By using the device to measure the error characteristic, the data of the whole process can be compared, and the error characteristic measurement of the straight-through current transformer DC magnetic bias can be carried out, and the DC magnetic bias error characteristics of the current transformer coils made of different iron core materials can be verified.
