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

Impact of time parameters of lightning impulse on the breakdown characteristics of oil paper insulation

open access: yesHigh Voltage, 2016
At present, the insulation performances of electrical apparatus under lightning impulse voltages are always evaluated by the withstand test of standard lightning impulse voltage (1.2/50 µs), which is recommended by IEC Standard.

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.
