CALIBRATION OF A SYSTEM FOR THE MEASUREMENT OF COMPLEX VOLTAGE RATIOS
R. Rybski, J. Kaczmarek
Abstract:
A calibration method for a system designed to measure complex voltage ratios is presented. The method is based on the application of an AC transformer bridge. The system comprises a multichannel data acquisition board with simultaneous sampling, input adaptation circuits and dedicated software. An analysis of the accuracy of the proposed calibration method is made. Experimental tests of the calibration system were performed for signals differing in phase by π/2 and π at frequencies from 50 Hz to 1 kHz.
