Impulse Characteristics of Highly Wetted Soils [PDF]

open access: yesJournal of Electrical and Electronics Engineering, 2023
It has been well accepted that under high impulse conditions, ionisation process in soil would occur, causing the ground resistance value to fall to a lower value than that obtained at low voltage low current, RDC.

Characteristics of Impulse Carburization LPC Process [PDF]

open access: yesMaterials, 2021
In the present work, Pyrowear53 steel was subjected to the impulse carburizing LPC process. After carburation, the material was quenched and tempered. Postprocessing analyses included the measurement of hardness, carbon content, residual austenite, and residual stresses.

Impulsive Breakdown Characteristics of Solid–Gas Interfaces [PDF]

open access: yesIEEE Transactions on Plasma Science, 2021
Comprehensive knowledge and understanding of the breakdown behavior of solid-gas interfaces are important for the development, optimization, and coordination of insulation in practical high-voltage (HV) gas-insulated systems (GISs) that are widely used in the power and pulsed power industries.

Effectiveness of Large Soil Grain Sizes in Studying Impulse Characteristics of Soil

open access: yesEnergies, 2022
There have been many published studies analysing the impulse characteristics of soil and various soil properties. Some of these published results are found to be largely different and inconsistent from one study to another. Soil properties may be complex

A New Flexible Graphite Composite Electrical Grounding Material

open access: yesFrontiers in Materials, 2022
Corrosion is an inevitable problem of metallic grounding grids. To propose an effective method avoiding the above corrosion, a new type of non-metallic grounding material was made in this paper. It is called flexible graphite composite grounding material,
