Partial Discharge Measurements of Voids in Layered Polymers and Cable Sample

Partial discharge (PD) data collected from testing on thin film layered polymer samples, and cable sample with artificial void. Data collected in accordance with IEC 60270. Equipment Data was captured using either a using an HFCT and a LeCroy Waverunner 104Xi oscilloscope or a Lemke Diagnostics LDS-6 partial discharge measurement system. Voltage Samples were stressed under AC, positive DC, and negative DC voltages (PDIVs included). Material Thin film samples of low-density polyethylene (LDPE) and polypropylene (PP), and a sample of cross-linked polyethylene (XLPE) were tested. Void Thin film samples contained 1mm voids of the following configurations. Single void – one void in the centre layer of material, parallel voids – two voids in the centre layer of the centre layer of material 1 mm apart, serial voids – two voids in each of the layers on either side of the centre layer, aligned as closely as possible. The cable sample contained a single 4 mm void. Scale Data was captured at two scales. On the scale of a single 50 Hz cycle, and the scale of individual PD pulses. Format The LDS-6 records data as .txt files, while the 104Xi records data as .csv files. Both of these are provided, as well as the data as .mat MATLAB data files.

本数据集包含针对薄膜层状聚合物样品与含人工气隙的电缆样品开展测试所采集的局部放电（Partial Discharge, PD）数据，所有数据采集均符合IEC 60270标准。数据采集采用两种配置方案：其一搭配高频电流互感器（HFCT）与LeCroy Waverunner 104Xi示波器，其二采用Lemke Diagnostics LDS-6局部放电测量系统。测试样品所施加的电压类型包括交流、正极性直流与负极性直流，涵盖局部放电起始电压（Partial Discharge Inception Voltage, PDIV）。测试所用薄膜样品的材质为低密度聚乙烯（LDPE）与聚丙烯（PP），另有一款交联聚乙烯（XLPE）电缆样品参与测试。薄膜样品内置尺寸为1mm的人工气隙，共三种结构形式：单气隙——在样品中心层内设置单个气隙；平行气隙——在中心层内设置两个间距1mm的气隙；串联气隙——在中心层两侧的各层中分别设置两个气隙，且尽可能保持对齐。本次测试的电缆样品内置单个尺寸为4mm的气隙。数据采集包含两种观测尺度：单50Hz工频周期尺度，以及单局部放电脉冲尺度。数据存储格式方面，LDS-6系统采集的数据存储为.txt文本文件，LeCroy Waverunner 104Xi示波器采集的数据存储为.csv逗号分隔值文件；上述两种格式的数据均已提供，同时还附带.mat格式的MATLAB数据文件。
