An Electronic Transformer Calibrator Based on Multiple Approaches
With electronic transformers gradually being launched on the market, there is still no unified standard for electronic transformer calibration in China. According to this situation, two methods for electronic transformer calibration, the direct method and the difference method, were studied in this paper. Based on the virtual instrument technology, a novel electronic transformer calibrator compatible with both the direct method and the difference method was designed. This system is able to meet the calibration needs for electronic transformers with digital output and analog output at the same time. While using the spectrum leakage compensation algorithm, the calibration accuracy of this system is also enhanced.
