At present, our country power quality national standard was chiefly stipulated five quotas: frequency, harmonic and voltage deviation, three-phase unbalance and the voltage fluctuation and flicker.
目前我国电能质量国家标准主要规定了五个指标：频率、谐波、电压偏差、三相不平衡及电压波动与闪变。
Objective To explore actual value on two methods between standard deviation by calculating one third of CLIA 88 permitted error and actual standard deviation in internal quality control.
