Efficient metrics for the detection of partial discharges under steep-fronted voltage pulses

PD measurements in RF with a Vivaldi antenna as a consequence of a sudden voltage change. The data is sorted by the amplitude of the applied voltage. The data also include the voltage impulse applied on a twisted pair. All files include 50 events of the output of the antenna and the corresponding voltage impulses to have statistical reliability. Six sets of .mat (Matlab) files with 50 samples of PD and voltage impulses sampled at 20 GSps. The time vector can be constructed with the sampling frequency and the number of samples. The name of the files contains information on the voltage peak which helps to determine the activity of PD: Vivaldi300A -> 300 means a voltage peak of 300V. 'A' means that the data is from the antena. Vivaldi300V -> 'V' means that the data is for the voltage impulse.针对突发电压变化引发的射频（Radio Frequency, RF）局部放电（Partial Discharge, PD），采用维瓦尔第（Vivaldi）天线采集的测量数据集。该数据集按照施加电压的幅值进行排序，同时包含施加于双绞线的电压脉冲数据。所有文件均包含50组天线输出与对应电压脉冲的事件样本，以保障统计可靠性。本数据集包含6组.mat（Matlab）格式文件，其中存储了以20 GSps采样率采集的50组局部放电与电压脉冲样本，可通过采样率与采样点数构建时间向量。文件名包含与电压峰值相关的信息，可用于判断局部放电的活跃程度：如Vivaldi300A中的"300"代表电压峰值为300V，"A"表示该数据来自天线；Vivaldi300V中的"V"表示该数据对应电压脉冲。
