“…Generally, the lead break should generate an acoustic signal with an amplitude of at least 80 dB for a reference voltage of 1 mV and a total system gain of 80 dB [25]. In [26], the sensitivity of sensors is verified using this method, and the measured value is 90dB.…”

“…It is reported that cross-linked polyethylene (XLPE) cables fail during operation while they have passed factory tests successfully [43]. AET has the potential to evaluate degradation and to predict the failure of XLPE cables [26]. XLPE cables degrade during operation due to water-treeing, thermal stresses, transient over-voltages, manufacturing defects, and corrosions [44][45][46][47].…”

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 acoustic sensors employed for capturing signals is studied. In the next step, the acoustic method of PD measurement is compared with the standard electrical method. Afterward, the applications of AET in PD measurement in different equipment are summarized. All acoustic method and combined acoustic-electrical method for PD localization in transformers are discussed. Moreover, the applications of AET in the monitoring of GIS systems are explained, along with the acoustic behaviors of moving particles in these systems. Finally, the general considerations in the signal processing of the acoustic signals are reviewed.

In this research, digital image processing method (DIPM) is used as an innovative approach to predict precisely the shape of electrical tree (ET) in cross-linked polyethylene (XLPE) power cables in the presence of air voids based on the field calculation using finite-element method (FEM). With the help of DIPM, two case studies are held to detect the accurate parameters of either the first initiated major branch or the tips of the major branches of ET. A hyperbolic needle-to-plane simulation model is proposed to illustrate the ET inception and propagation stages. The non-uniform electric fields thatare accompanied with the electrical treeing phenomenon are calculated using FEM as one of the most effective numerical methods to deal with non-uniform shapes. The predicted shapes of ET initiation and growth are provided in an innovative manner with the implemented hybrid connection between FEM and DIPM for the two proposed case studies. Direction branching approach and deviation angle branching approach are provided in this work to predict the shape and the direction of ET branched voids. The validity of the proposed model is assessed with the help of available previous experimental and simulation data.

“…Due to the complexity of calculating the nonuniform electric fields arisen that arisen from the needle electrode tip that mimics the protrusion tip, the accurate distribution of these fields is an urgent process to be calculated using the powerful effective numerical methods not the traditional physicalanalytical approaches [18][19][20][21]. Numerical methods are classified as the magic tools to deal with the complicated mathematical and physical problems like the scope of this research.…”

“…As the proposed model in this work is bounded area and associated with a complicated random shape of ET, FEM is the most effective numerical method to be used in this case study. Regarding to mesh generation approach, FEM analysis can simplify the complicated problems into small elements to facilitate the analysis under the satisfaction of the applied constraints [20][21][22][23].…”

This paper investigates the effect of the voltage variations and the change of solid insulation material on the initiation and propagation of Electrical Tree (ET) through solid dielectrics based on the application of Finite Element Method (FEM) approach using the environmental domain of [COMSOL Multiphysics ] program as an innovative way to be used in the complicated study of Electrical Treeing Phenomenon (ETP). This research provides an innovative solution to suppress the initiation point of ET and suppress its growth rates using a composite solid insulation material of Poly-Vinyl Chloride (PVC) and Cross-Linked Polyethylene (XLPE) regardless to the mechanical features of this composition. In this research, the study cases are conducted for High Voltage (HV) and Extra High Voltage (EHV) power system networks as the effect of ETP is to be observed clearly. The simulation model is used in this research to imitate the proposed hyperbolic needleplane system. Case studies are compared between each others to validate the results
