Electron dynamics in high power impulse magnetron sputtering discharges [PDF]

open access: yes, 2019
Electrons are the main energy carriers in HiPIMS discharges and their properties govern the ionization processes and thus the discharge properties. The properties of the electrons are described by the fundamental plasma parameters, such as the electron ...

The Estimation of Lightning Impulses Superimposed onto Pre-Stressed DC Breakdown Voltages Using the Leader Propagation Method

open access: yesEnergies, 2022
The impulse breakdown attributes are of rudimentary importance in the insulation coordination in the gas-insulated switchgear (GIS). The critical voltage waveshape for the insulation is the surge over voltages.

Impulse-driven surface breakdown data : a Weibull statistical analysis [PDF]

open access: yes, 2012
Surface breakdown of oil-immersed solids chosen to insulate high-voltage, pulsed-power systems is a problem that can lead to catastrophic failure. Statistical analysis of the breakdown voltages, or times, associated with such liquid-solid interfaces can ...

Investigations on the Performance of Grounding Device with Spike Rods (GDSR) with the Effects of Soil Resistivity and Configurations

open access: yesEnergies, 2020
In a recently published work, the characteristics of a new grounding device with spike rods (GDSR) with various arrangements of ground electrodes under high magnitude impulse currents (up to 16 kA), was investigated.

Performance of earthing systems at steady-state and under impulse conditions [PDF]

open access: yes, 2013
It is important to have a proper protection system in order to protect any equipments from high currents. High impulse currents can be caused by lightning, temporary over voltages and over loading.
