The development of the power industry has also led to the upgrading of power equipment, and the new AC/DC current transformer has received extensive attention due to its practical value, and also triggered the demand for new transformer calibration methods. This paper designs an AC/DC current transformer calibration device based on LabVIEW high-speed data acquisition system, which is mainly divided into two parts. The first part introduces a new type of transformer calibration method, describes the internal structure and operation principle of the device in detail, introduces the module configuration and specific functions of the data acquisition system, and shows the equipment prototype. In the second part, the corresponding traceability test circuit is designed, the traceability data is obtained through prototype test, and the accuracy of the equipment is verified.
