UK Power station transformer dissolved gas analysis data [2010-2015]

These are supplementary data, as cited in Lewis, Wild, Allcock and Walach (2022), "Assessing the impact of weak and moderate geomagnetic storms on UK power station transformers", published in the journal "Space Weather". The accompanying files include dissolved gas analysis records from coolant oil in 13 UK power station transformers for various timespans between 2010-2015. The dissolved gas analysis files are presented in comma separated variable format, one file for each of the 13 transformers. Each file includes a header line describing the content of each "column" of data. After this header, each line includes one record corresponding to the timestamp indicated in the first column (in Universal Time). Data are recorded in units of parts per million (ppm). With the exception of Transformers C and D, concentrations of 8 trace gases are recorded in each phase of the transformer. For Transformers C and D, concentrations of 8 trace gases are recorded in one phase only. The authors thank D. Barker, EDF Energy Nuclear Generation, for providing these data. Also included is a file containing a list of geomagnetic storms in this period, an extended version of the list included in Walach & Grocott (2019) [https://doi.org/10.1029/2019JA026816]. The file presenting the list of geomagnetic storms is presented in a column-separated format, with a simple header row. Please cite Lewis et al (2022) if using any of these data. Description

本数据集为补充数据，援引自Lewis、Wild、Allcock与Walach（2022）发表于《空间天气（Space Weather）》期刊的论文《弱中度地磁暴（geomagnetic storms）对英国电站变压器的影响评估》。随附文件包含2010至2015年间多个时段下，13台英国电站变压器冷却油的溶解气体分析（Dissolved Gas Analysis, DGA）记录。所有溶解气体分析文件均采用逗号分隔值（Comma-Separated Values, CSV）格式，13台变压器各对应一份文件。每份文件首行均为表头，用以说明各数据列的内容；表头之后的每一行对应第一列所标注的世界时（Universal Time, UT）时间戳的一条记录，数据单位为百万分比（parts per million, ppm）。除变压器C与D外，其余11台变压器的各相均记录了8种痕量气体的浓度；而变压器C与D仅在单相中记录了8种痕量气体的浓度。作者感谢EDF Energy Nuclear Generation的D. Barker提供本数据集。本数据集还包含一份对应此时段的地磁暴列表文件，该列表是Walach与Grocott（2019）所附列表的扩展版本，原始列表详见文献[https://doi.org/10.1029/2019JA026816]。该地磁暴列表文件采用列分隔格式，配有简易表头行。若使用本数据集，请引用Lewis等人（2022）的研究。说明
