Statistical analysis for internal and surface discharges identification in XLPE insulation under AC voltages

2017 International Conference on High Voltage Engineering and Power Systems (ICHVEPS), 2017
One of the most effective methods to assess the quality of solid insulated cable under AC or DC voltage is partial discharge (PD) analysis. Several common methods to analyze PD phenomenon based on PD data sets, such as PD magnitude, phase, and occurrence time, have been investigated and interpreted.

Surface and Internal Discharge Propagation With the Liquid-Conductive Solid Interface Based on the Migration-Ohmic Model

IEEE Transactions on Magnetics, 2019
As an insulator, dielectric composites should be guaranteed the specific level of insulation performance to maintain the electric device. It is essential to understand the physical phenomena at the interface of the dielectric composites, where the electric field and charge distribution are concentrated.

Assessment of Energy Consumption and Internal Stresses in Surface Layer in the Abrasive Electro-Discharge Grinding (AEDG) Process

Defect and Diffusion Forum, 2013
In this work, results have been presented related to the influence of selected electrical parameters of the AEDG process on the energy consumption and state of the internal stresses in the outer layer at this stage of the process, in comparison with conventional grinding.
