This paper reviews the main features of acoustic emission technique. First, the
characteristics of acoustic signals and their physics are addressed. Then, the structure of …

It is well known that a correlation exist between the pattern of partial discharge (PD)
behavior and the insulation quality. Since different sources of partial discharge have their …

Partial discharge (PD) measurements provide valuable information for assessing the
condition of high voltage (HV) insulation systems, contributing to their quality assurance …

Recent research has shown that the wavelet transform (WT) can potentially be used to
extract partial discharge (PD) pulses from severe noise. However, the method is more …

The rapid discharge of a dc-link capacitor of the voltage-source converter (VSC)-based dc
system is the primary indication of the fault condition. Apart from the time-domain analysis …

Online partial discharge (PD) measurements have long been used as an effective means to
assess the condition of the stator windings of large generators. An increase in the use of PD …

Wavelet shrinkage methods are effective for de-noising of partial discharge (PD) detection.
Base wavelets are related to distortion of PD signals de-noised by wavelet shrinkage …

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 …

This article develops a fully automatic tool for the de-noising of partial discharge (PD)
signals occurring in electrical power networks and recorded in on-site measurements. The …

Optimal selection of features of Partial Discharge (PD) signals recorded from defects in High
Voltage (HV) cables will contribute not only to the improvement of PD pattern recognition …
