摘要
针对目前电压互感器(TV)相关参考书中电磁式TV误差模型向量几何图建模方法存在的缺陷问题,文中提出了一种基于矢量代数的误差建模方法,并对电磁式TV误差进行了系统、全面的分析,对电磁式TV误差的计算及电能计量影响进行了阐述,从而使广大电能计量技术人员对电磁式TV误差理论有了更清晰地了解。
Targeting at the disadvantages of current modelling methods, a vector diagram is adopted to construct and analyze TV error mathematical model in this paper. With the model established using vector diagram, the errors of TV are analyzed systematically and comprehensively. Also, the influence of the TV error on the electric power energy metering is elaborated. It helps technicians of the electric energy metering to know more about TV error theory.
