Flashover Voltage Dataset for Polymeric Insulators under Environmental Conditions

This dataset contains flashover voltage records for polymeric insulator samples obtained through laboratory experiments conducted in a controlled environmental chamber under humidity, ageing, and pollution-related conditions. The dataset includes four polymeric insulator samples. The Excel workbook includes separate sheets for individual samples and a final sheet named “Whole samples”. The “Whole samples” sheet contains the complete dataset, combining all four polymeric insulator samples, and should be used as the main dataset sheet. Each record contains geometry-related variables, relative humidity, accelerated ageing, non-uniform pollution degree, occupation ratio, salt deposit density, and the corresponding flashover voltage. The complete dataset contains 6,656 records and 10 columns.本数据集收录了在可控环境试验箱内，于湿度、老化及污染相关工况下开展实验室实验所得到的聚合物绝缘子（polymeric insulator）样品闪络电压（flashover voltage）记录数据。本数据集共包含4组聚合物绝缘子样品。 该Excel工作簿包含针对单组样品的独立工作表，以及一张名为"Whole samples"的汇总工作表。"Whole samples"工作表收录了合并全部4组聚合物绝缘子样品的完整数据集，应作为本数据集的主工作表使用。 每条记录均涵盖几何相关变量、相对湿度、加速老化工况、非均匀污秽度、污层覆盖占比（occupation ratio）、盐沉积密度（salt deposit density）以及对应的闪络电压。本完整数据集共计6656条记录，包含10个数据列。
