Space Charge Modulated Electrical Breakdown. [PDF]

open access: yesSci Rep, 2016
AbstractElectrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20thcentury, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the explanation for dc breakdown strength being twice or higher than ac breakdown strength in ...

Degradation patterns of silicone-based dielectric elastomers in electrical fields [PDF]

open access: yesInternational Journal of Smart and Nano Materials, 2018
Silicone elastomers have been heavily investigated as candidates for the flexible insulator material in dielectric elastomer transducers and are as such almost ideal candidates because of their inherent softness and compliance.

Synergistic improved electrical resistivity-temperature characteristics and DC breakdown strength in insulating XLPE composites by incorporating positive temperature coefficient particles

open access: yesPolymer Testing, 2023
Weakening the electrical resistivity-temperature dependence of cross-linked polyethene (XLPE) is an effective way to enhance the electric field uniformity of high-voltage direct current (HVDC) cables.

Statistical Analysis of Mechanical Strength and Dielectric Breakdown of Polyester Nano-Alumina Composites [PDF]

open access: yesJournal of Applied Sciences and Nanotechnology, 2023
The mechanical and electrical properties relation are very important, especially for brittle material. Nano Alumina-unsaturated polyester (PS/Al2O3) composites were prepared by casting PS with different percentages (1, 2, 3, and 4 wt%) of Nano alumina ...

Electrical tree modelling in dielectric polymers using a phase-field regularized cohesive zone model

open access: yesMaterials & Design, 2023
Electrical treeing is a leading cause to the eventual breakdown of dielectric polymers under high voltages. This paper presents a simulation scheme developed based on the phase-field regularized cohesive zone model (PF-CZM) for electrical tree modelling.

Electrical breakdown in tissue electroporation [PDF]

open access: yesBiochemical and Biophysical Research Communications, 2015
Electroporation, the permeabilization of the cell membrane by brief, high electric fields, has become an important technology in medicine for diverse application ranging from gene transfection to tissue ablation. There is ample anecdotal evidence that the clinical application of electroporation is often associated with loud sounds and extremely high ...

Electrical response and pore structure evolution affected by cyclical plasma breakdown

open access: yesMeitan xuebao, 2023
Artificial improvement of coal seam permeability is the key to solve the low gas drainage efficiency and prevent gas dynamic disaster. Plasma based on physical discharge is one of the effective means of coal seam antireflection. However, previous studies
