摘要
在模拟方法的基础上，制定了数字输入电能的测量标准。采用电容补偿的电阻分压器和电流分流;采用非积分周期采样技术减小了算法误差。本标准的工作频率为45 ~ 65hz，电压范围为60v ~ 380v，电流范围为0.2 A ~ 20a。
A digital input electricity energy measurement standard
A measurement standard of digital input electricity energy based on the analog based method was developed in NIM China. The resistive voltage divider and current shunt with capacitor compensation were adopted; the non-integral period sampling technology was used to reduce the algorithm error. The working frequency of this standard is 45 to 65 Hz, the voltage range is 60 V to 380 V and current range is 0.2 A to 20 A.
