Abstract:A design for multi-function power network measurement instrument based on DSP is presented. The operation pattern and interface of C501, C500 and AT93CA6 chips are discussed, measurement technique and error-correcting method are studied .This instrument can make the real-time measurement of three-phase current, voltage, power factor, active power, reactive power, apparent power, frequency and energy. Its accuracy can reach to the class of 0.5.
Keywords:Metrology  Digital signal process(DSP)  Power network parameter measureing
