Abstract

We have used nanocrystalline powder to build a core for Rogowski coils suitable for application in energy meters. The sensor linearity error is 0.32% of full scale (FS) of its 20 A range, which is acceptable for this application. The main advantages of the new core are 15-fold increase in sensitivity, which results in lower noise, and high rejection of direct current. It operates at up to 1000 A dc with 20% change in sensitivity. Resulting accuracy of power measurement using a single-chip digital power meter is 0.22% FS.

铁磁性粉末磁芯Rogowski线圈

我们已经使用纳米晶体粉末为Rogowski线圈构建了适用于能量计的磁芯。传感器线性误差为其20A范围的满刻度（FS）的0.32%，这对于该应用是可接受的。新磁芯的主要优点是灵敏度提高了15倍，从而降低了噪声，并具有很高的直流抑制率。它在高达1000 A dc的电压下工作，灵敏度变化20%。使用单片数字功率计进行功率测量的结果精度为0.22%FS。

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.
