Signal denoising techniques for partial discharge measurements [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2005 One of the major challenges of on-site partial discharge (PD) measurements is the recovery of PD signals from a noisy environment. The different sources of noise include thermal or resistor noise added by the measuring circuit, and high-frequency sinusoidal signals that electromagnetically couple from radio broadcasts and/or carrier wave communications.
