Design of Calibration platform for DC current transformer based on LabVIEW

According to the verification requirement of DC current transformer, a multi channel DC transformer calibration platform based on virtual instrument is designed and built. Using Laboratory Virtual Instrument Engineering Workbench (LabVIEW) programming, it can play a flexible, customizable, powerful data processing and analysis functions. The verification platform includes three parts, the multi-channel data acquisition, the LabVIEW processing platform and the RS485 bus. Data acquisition part uses 16 channels synchro-nous sampling. The experimental results show that the method based on the virtual instrument calibration method is convenient and effective, and it can improve the efficiency and the automation level of the mutual verification.
