    • Acoustic partial discharge signal denoising using power spectral subtraction 

      Hussein, Ramy; Shaban, Khaled Bashir; El-Hag, Ayman H. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      Measuring partial discharge (PD) phenomena in power transformers is often conducted by acoustic emission (AE) method. However, many interference sources are usually encountered with the captured PD signals which negatively ...

    • Wavelet Transform with Histogram-Based Threshold Estimation for Online Partial Discharge Signal Denoising 

      Hussein, Ramy; Shaban, Khaled Bashir; El-Hag, Ayman H. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      Online condition assessment of the power system devices and apparatus is considered vital for robust operation, where partial discharge (PD) detection is employed as a diagnosis tool. PD measurements, however, are corrupted ...
