Abstract
Wide range fluctuation of electrical load leads the large measurement error of traditional electric energy me -ter.This paper designed a high precision data acquisition system for 0.05 class three-phase standard energy meter . The system is composed of FPGA and high precision data acquisition circuit .The high precision data acquisition cir-cuit consists of signal modulate circuit and 24 bit A/D converter, and the sampling rate is up to 52.73 kHz, which meet the requirement of acquisition precision .The precision of acquisition system is test by acquiring D .C.voltage signals, and the error is less than 0.02%.关键词
