中文摘要:

针对目前参考书等文献关于PT二次压降模型建立及分析采用向量图几何分析法存在的缺陷问题,本文采用了逻辑严谨的矢量代数分析法,对PT二次压降进行了数学建模,并对PT二次压降进行了系统、全面的分析,对PT二次压降的计算及电能计量影响也进行了全面阐述,对广大电能计量技术人员系统了解PT二次压降理论提供有益帮助。

英文摘要:

At present, vector diagram was adopted to help the construction and analysis of the PT secondary loop voltage drop’s mathematical model. To solve the defects in the vector diagram geometric analysis method, in this paper, algebraic analysis method was chose. The method was used in the mathematical model re-construction and systematical analysis of the PT secondary loop voltage drop. In the article, the influence of the PT secondary loop voltage drop on the electric power energy metering was elaborated. And it provided a useful help to understand the voltage drop theory for metering technical staff.
