摘要
谐波对电能计量的准确性影响较大。首先探讨谐波对仪用电压电流互感器精度的影响 ,然后通过具体实验 ,利用新研制的基于虚拟仪器技术的多功能电能计量装置与传统的感应式电能表在不同的谐波条件下同时计量电能 ,对二者结果进行对比分析 ,得出谐波对感应式电能表计量影响的准确数据 ,并总结其规律。
The harmonic components bring on higher influence to the metering of electric energy.In this paper ,the influence of harmonic to the accuracy of potential transformer and current transformer is studied firstly, and then through some experiments, the new equipment-multifunctional metering of electric energy equipment based on virtual instruments technology and traditional induction Watt\|hour meter to measure the power at different harmonic situations.Their results were analysed,and the exact data of the influence of harmonic to the metering of electric energy was got Finally, their rule will be summed up
