为了确定用电设备导致的低功率因数对电能计量装置产生的影响，文章从理论角度分析了功率因数降低对电能质量的影响，并通过实验验证了电能表在相同视在功率不同功率因数情况下的计量性能。实验结果表明，用电设备功率因数越低，产生的无功功率越大，线路的损耗越多，使得电能计量装置误差也越大。

In order to clarify the impact of low power factor on electric energy metering , The relationship between the power factor and power quality is analyzed from a theoretical perspective in this paper ., and the electric energy mete-ring performance is validated by experiments with different power factors adopted but the same apparent power value . Experimental results show that the lower the power factor of electrical equipment is taken , the larger reactive power will be generated , the greater loss of the line will be brought in , and the more error the energy metering device will produce.
