Analysis and Modeling of Wideband RF Signals Induced by PD Using Second-Order Statistics

In several measurement campaigns in substations reported in Chap. 3, wideband impulsive noise waveforms emitted by partial discharges are transient, their samples are correlated and their power spectral densities have approximately a form of ∼ (f − f0)−γ, where f0 is the resonant frequency of the RF measurement setup and γ > 0 an arbitrary exponent.
