五次、七次谐波对电度表计量的影响

Infection of all kinds of electric energy meter in five and seven degree harmonic

通过用失真波标准功率源模拟现场五次、七次谐波含量对电度表影响的实测值与理论值的比较,得出电子式标准电度表及ABBAINRTL安装式电度表在谐波下其有功计量都一致而无功测量存在差异的结果,并对其原因作了分析,提出了解决方案。

Influence of using anamorphic wave power simulated fifth and seventh harmonic on all kinds of electric energy meter and compared with theory count and actual measure-ment.Available power measure of the standard electric energy meter and the ABB meter in harmonic was identical result and that reactive power measure had difference and resolvent are found out.
