Impulse Characteristics of Highly Wetted Soils [PDF]
Journal 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.

Effectiveness of Large Soil Grain Sizes in Studying Impulse Characteristics of Soil [PDF]
Energies, 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

Effect of Impulse Polarity on a New Grounding Device with Spike Rods (GDSR) [PDF]
Energies, 2020 The characterizations of grounding systems subjected to high impulse conditions are known to be dependent on the polarity, current to peak time and discharge time, as well as the electrical properties of the soil, and the grounding electrodes themselves.

Measuring method for partial discharges in a high voltage cable system subjected to impulse and superimposed voltage under laboratory conditions [PDF]
International Journal of Electrical Power & Energy Systems, 2020 A partial discharge (PD) measuring system has been deployed in order to identify and measure PD in a high voltage (HV) cable joint under impulse and superimposed voltages under laboratory conditions. The challenge is to enable the detection of PD during the impulse conditions. The method of measurement has been investigated by introducing an artificial

High power impulse magnetron sputtering under industrial conditions [PDF]
, 2011 In this thesis, the recent development step of magnetron sputtering, termed high power impulse magnetron sputtering (HiPIMS) has been studied. Compared to conventional magnetron sputtering HiPIMS provides a higher plasma density which can ionise the sputtered material.
