The article compares three different methods for reducing noise in partial discharge (PD) measurement data: discrete wavelet transform, wavelet packet transform, and stationary wavelet transform. These techniques have all been successful in removing unwanted noise from PD data. The study looked at how well each method worked and how long it took to process the data.
