The paper analyses how the characteristics of medium-voltage network with insulated neutral and conditions under which single line-to-ground fault occurs (insulation condition value resistance) influence zero-sequence components voltage transformer station bus bar, current, currents faulted line other non-faulted power lines connected to bars. Assuming waveform medium voltages in is known, resi...

This paper presents a numerical study of the system unbalance and the fault impedance effect on faulted power system analysis. Two short circuit techniques, the symmetrical components and phase components algorithms are implemented and analyzed based on numerical simulations of the IEEE 13 bus test feeder. Test cases include voltage unbalance effect and fault impedance effect on during-fault vo...

Single crystals of stoichiometric MgA1204 spine1 were neutron-irradiated to fluences (> 0.1 MeV) of 2.8 x loz5 n m-2 (1.5 dpa) at 1015 K and 1.9 x loz6 n m-2 (10 dpa) at 925 K and 1 100 K. The resulting point defect'aggregates were investigated using bright-field and weak-beam dark-field transmission electron microscopy. For the higher dose, faulted interstitial Frank dislocation loops were fou...

Analysis of TanDEM-X and Shuttle Radar Topography Mission (SRTM) data reveals geomorphic evidence for 292 fault-propagation fold scarps across the Miocene Nullarbor Pliocene Roe Plains in south-central Australia. Vertical displacements (VD) are determined using topographic profiling a subset (n = 48) traces. Fault dips (mean 44 +16/−14° at 1σ) estimated from seismic reflection data; mean dip is...

This paper investigates the role of stacking fault (5%, 20% and 50%) morphology Li2MnO3 lamellar materials, issued from coprecipitation method with three annealing temperatures, on surface reactivity. The structure have been characterized by XRD, SEM TEM. We studied reactivity these materials combining X-ray photoemission spectroscopy (XPS), gaseous adsorption first-principle calculations. An e...
