摘要
中国国家高压计量中心(NCHVM)和澳大利亚国家计量研究院(NMI)对电压互感器(VT)的电压比和相位移进行了测量比较,并将中国国家高压计量中心提供的两台电压互感器作为巡回标准。两个机构测量的 10 kV/100 V 电压互感器的电压比相差小于 5 μV/V,相位移差小于 6 μrad,而 (110/p3 kV)/100 V 电压互感器的电压比相差小于 16 μV/V 和 13 μrad。这些结果证实,两家机构的测量结果在详细的测量不确定度评估范围内是一致的。对比结果进一步增强了人们对这两种方法的信心,这两种方法被广泛用于电力行业的电压互感器校准。
Comparison of voltage transformer measuring systems at 110 kV and 10 kV
A comparison of measurements of voltage transformer (VT) voltage ratio and phase displacement was performed between the National Center for High Voltage Measurement (NCHVM), China and the National Measurement Institute (NMI), Australia, with two voltage transformers provided by the NCHVM being used as the travelling standards. Voltage ratios of the 10 kV/100 V transformer measured by the two institutes differed by less than 5 μV/V and the phase displacement by less than 6 μrad, while voltage ratios of the (110/p3 kV)/100 V transformer differed by less than 16 μV/V and 13 μrad. These results confirmed that measurement results of the two institutes agreed within detailed measurement uncertainties evaluation. The comparison further enhances the confidence in both methods, which are widely used for calibration of voltage transformers in the electricity industry.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
