Electronic Instrument Transforme calibration related to the safe operation of the grid and the energy measurement, trade settlement fairness. This article briefly describes the classification and electronic transformer calibration methods commonly used in the LabView software environment, using zero-phase digital filter to filter white noise signal, using Hanning convolution ab-solute calibration method for digital signal two quasi-synchronous digital signals to achieve the fundamental parameters score analy-sis, implementation of a virtual instrument electronic transformer calibration method. Experimental data show that the method can be used to test class 0.2S transformer, has a practical application value.
