Effect of the Error of Measurement of Current Harmonics on the Accuracy of Determination of Magnetic Characteristics

Resumo

The effect of the error of measurement of the form of current harmonics on the accuracy of determination of weber-ampere characteristics of electrical devices is studied. The developed method for determining weber-ampere characteristics makes it possible to plot them for ac electrical devices in terms of the amplitude and frequency of the input voltage and of the measured current waveform. The effect of the error of measurement of the waveform on the weber-ampere characteristic obtained is studied.
