The Calibrator for Electronic Transformers Based on Multiple Approaches
Bao Xiang Pan · Keisou gijutsu · 2013
With the electronic transformer gradually being launched on the market,there's still no unified standard for the domestic electronic transformer calibration. According to this situation,two electronic transformer calibration methods,the direct method and the difference method,are studied. Based on the virtual instrument technology,a novel electronic transformer calibrator compatible with both the direct method and the difference method is designed. This system meets the calibration requirements for the electronic transformers with digital output or analog output at the same time. It extends the application of the calibrator and improves its reliability. While using the spectrum leakage compensation algorithm,the calibration accuracy of the system is also enhanced.
