摘　　要：采用填脉冲式相位测量方式设计工频相位计,使用Atmega8作为主控制器,通过RS-485总线远程测量工频相位。相位测量的分辨率为0.1度,文章分析了产生误差的因素。A phase meter was designed with filling pulse method. It used Atmega8 as main controller. The phase meter applied RS- 485 bus to measure phase at a distance. The resolution was 0,1 degree, the error factors was analyzed in the paper,
