The goal of this paper is development ofa DSP based three phase power quality analyzer. Power analysis algorithm is a correlation function and it is accomplished using stand alone type TMS320C31 DSP(digital signal processor)board. Results of power analysis are displayed by LCD and D/A converter on the proposed system. Finally, this paper also goes on to discuss the performance of an instrument prototype, compared with one of those foreign models, both in terms of accuracy and speed of measurement.
