Description
Summary:In this paper a complete data acquisition and signal processing PC based harmonic power analyzer system is proposed, designed, implemented, and the results are presented. A software designed digital filter is used to replace the traditional analog antialiasing filter. The complete system has shown an overall voltage sensitivity of /spl plusmn/0.6 V up to 400 V rms, current sensitivity of /spl plusmn/9 mA and an accuracy of /spl plusmn/0.16 Hz at an operating frequency of 50 Hz. The complete system was implemented and successfully tested.
