Acoustic emission (AE) is the transient elastic waves within a solid material caused by the rapid release of localized stress energy such as the formation of cracks when a material is subject to mechanical loading. This study investigates AE-signals generated from internal manufacturing flaws embedded...
AEPs were used to create a source localization model, which is described below. Bad channels, identified through visual inspection, were interpolated using spherical spline interpolation34. Then eye blink and ECG (electrocardiogram) artifact activity were reduced using spatial filtering. Both artifact to...

This study reviews more than one hundred significant studies on various methods and advances in the detection of partial discharges (PD), with a specific focus on corona discharges (CD) in medium-voltage switchboards (MV) using the acoustic emission (AE) method. Furthermore, the challenges and...
Energy: The area under the detection envelope within the AE hit duration. Duration: The period between when the pulse first crosses the threshold until the last pulse threshold crossing Peak frequency: The maximum frequency detected in an AE wave spectrum. Centre frequency: The centre of gravity ...
Nowadays, hydropower plants are being used to compensate for the variable power produced by the new fluctuating renewable energy sources, such as wind and solar power, and to stabilise the grid. Consequently, hydraulic turbines are forced to work more of
