Examples

Here you can download a set of raw data examples in the different formats that can be read by PDflex.

 The purpose is to provide data the user can interact with and get familiar with PD pulse waveforms. Although they are meant to be illustrative data, the file name provides some information of the nature of the data.

Surface PD data set with disturbances, false triggers and low SNR

FileSizeComments
Surface_PD_noise1538 kBSurface PD measured in a test cell at +10kVDC and -10kVDC. The data set features signals with disturbances, false triggers or low SNR
Some signals show overflowing values at the end of the acquisition, this is added due to the settings of the scope and therefore they must be removed or ignored if you are processing this data set.
