TLDR
In this article, the theoretical sensitivity of conventional partial discharge detectors is compared with that obtained from ultra wideband (UWB) (up to l GHz) detection systems, and the comparison indicates that for relatively lossfree distributed systems, such as SF6 insulated bus, the UWB system is up to two orders of magnitude more sensitive.Abstract:
The theoretical sensitivity of conventional partial discharge detectors is compared with that obtained from ultra wideband (UWB) (up to l GHz) detection systems. The comparison indicates that for relatively lossfree distributed systems, such as SF6 insulated bus, the UWB system is up to two orders of magnitude more sensitive. UWB detection also embodies additional advantages such as facilitating the location of discharge sites and the rejection of external electrical noise. For discharge detection in plastic-insulated cables, true UWB detection is not practical because of frequency-dependent attenuation effects, although certain gains in sensitivity can be achieved with a detector bandwidth of up to 10 MHz.read more

Stochastic properties of partial-discharge phenomena
TL;DR: In this paper, the authors present a bibliography and survey of the literature concerned with theory and measurement of the stochastic behavior of pulsating partial discharge (PD) phenomena that can occur when insulation is subjected to electrical stress.

Noise Reduction Techniques in Electronic Systems
TL;DR: In this paper, the authors present new chapters on controlling the emission from electronic systems, especially digital systems, and on low-cost techniques for providing electromagnetic compatibility (EMC) for consumer products sold in a competitive market.

Extraction of Signals from Noise
TL;DR: This book is devoted to problems involving extraction of signals from a background of random noise, and takes into account both "white noise" and "correlated noise", which makes its treatment more general, and even simplifies it.
Extraction of Signals from Noise
L. A. Wainstein,V. D. Zubakov +1 more
TL;DR: In this paper, the authors focus on the problem of signal extraction from a background of random noise, by which they mean not only restoration of unknown (random) signals, but also detection of signals of interest.

Electromagnetic Techniques for Fault and Partial Discharge Location in Gas-Insulated Cables and Substations
TL;DR: In this article, the fault location in gas cables and partial discharge location for cables and substations were investigated. But the fault locations were not considered for the fully enclosed nature of gas insulated substations, which increases the difficulty of testing, maintaining, and troubleshooting the switchgear.
