Denoising Analysis of Partial Discharge Acoustic Signal Based on SVMD-PCA
Journal of Applied Science and Engineering, 2023 Partial discharge (PD) acoustic signal detection is one of the effective means to assess the insulation status of power transformers. In actual monitoring, white noise is likely to cause strong interference to the partial discharge acoustic signal of the

Influence of pressure on partial discharge spectra [PDF]
2016 IEEE Electrical Insulation Conference (EIC), 2016 In forecoming “more electrical aircrafts”, aircrafts will become more compact and light, as hydraulic, pneumatic or mechanical systems will be replaced by electrical ones. The network voltage is expected to increase far above Paschen’s minimum, thus increasing the risk of partial discharges.

A Physical Calibrator for Partial Discharge Meters [PDF]
Energies, 2019 This article offers an alternative method of calibrating partial discharge meters for research and teaching purposes. Most current modern calibrators are implemented as precise voltage pulse sources with a coupling capacitor. However, our calibrator is based on the physical principles of dielectric materials distributed in a plane or space.
