The Research And Development of a Digital Meter of Parameters of a Three-Phase Network on ADC ADS131E08

The research describes the results of the study of the developed digital meter of power quality parameters based on the ADS131E08 ADC. The structure of the developed meter is presented. The description of the structure of the selected sigma-delta ADC is given. The dependences of the signal/noise ratio on the sampling frequency are given. On the basis of the above development, a physical model was made.
