| Abstract: | A new-type calibrator for electronic current transformer is developed by using LabView.It is flexible, self-contained, capable of data processing and analyzing, and includes digital compensation .The system uses discrete Fourier transform method and digital compensation technology to accurately measure the ratio error, angle error, frequency, and harmonics of the signal. The new calibrator is portable,apt to expand the function.It has short construction cycle,high efficiency. |
