The calibration apparatus of transformer calibrator based on digital standard source

摘要：

The calibration apparatus of transformer calibrator provide a high quality sine signal source based on DDS synthesizer instead of traditional electrical method. The signal source generates three AC signals with the corresponding phase difference to calibrate transformer calibrator and it has a high accuracy and stability. The apparatus solves the problem that can’t be easily solved in traditional electrical methods, for example the changing the signal frequency to test sensitivity of apparatus. Using this apparatus to calibrate transformer calibrator, not only improve the accuracy, but also make the intelligent automatic measuring the errors of transformer calibrator come true.
