The Design of Electronic Transformer Sophisticated Calibration System Based on FFT Algorithm
The present work investigated a sophisticated calibration system based on the FFT algorithm for electronic transformers. The structure and the characteristics of LabVIEW were introduced in detail, at the same time, and the detailed demonstration of the process of harmonic analysis was given via FFT based on LabVIEW. Through these methods, the disturbance of the frequency leakage and the noise could be reduced and the detecting accuracy of the harmonic analysis could be improved. Serials of the experiments and error analysis were given, and the simulation results have verified the effectiveness and practicability of the algorithm for the electronic transformer calibration system.
