Aiming at the problems of distribution management and power quality improvement for large electricity us-ers,a new design of power quality intelligent diagnosis instrument based on dual high speed ATmega128L and Zigbee is proposed in this paper. The corresponding hardware interface circuit design,hardware program design and applica-tion in power quality have been introduced,and its feasibility has verified by field test. High precision MAX125 and ATmega128L are used for data synchronous acquisition,calculation,analysis,display,SD card storage and results record. Moreover,Zigbee is used for uploading data which are used for the upper system software to make power quali-ty analysis. Thus it will strengthen the electricity management for users,improve power quality and save energy as well. The instrument has advantages of easy portability,low cost,high precision,strong anti - interference ability and be easy to promote. Therefore,it can meet the needs of dedicated large users’power quality managements effectively.
