Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing

High Voltage, EarlyView.
ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.

First Investigations on High-Order Discretization Schemes for Finite Volume Methods in Cartesian Grids

, 2000
Based on a finite-volume method, a spatially fourth-order accurate scheme is proposed for solving the unsteady compressible Euler Equations for subsonic flows on Cartesian background grids in the frame of a Chimera method (Ref [1], [2]).

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

High Voltage, EarlyView.
ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

Fast eikonal phase retrieval for high‐throughput beamlines

Journal of Synchrotron Radiation, EarlyView.
Fast eikonal phase retrieval with complementary local (sub‐pixel) and non‐local (multi‐pixel) solvers strongly suppresses nonlinear streak artefacts in long‐distance propagation‐based phase‐contrast micro‐tomography at high computational efficiency.A fast eikonal phase retrieval formulation is introduced that accelerates eikonal phase retrieval by more

GIWAXS using microbeam applied in halide perovskite films for high spectral resolution and mapping capability

Journal of Synchrotron Radiation, EarlyView.
This article demonstrates that microbeam GIWAXS (µ‐GIWAXS) effectively overcomes the distorting footprint effects of conventional GIWAXS analysis of perovskite films. This advancement not only delivers higher reciprocal‐space resolution data but also unlocks the unique capability to spatially map microstructural inhomogeneity, which is vital for the ...

Mapping structure–property relationships in a 6‐oxo‐verdazyl radical by variable pressure crystallography and density functional theory

Acta Crystallographica Section B, EarlyView.
For the first time, the structural response to pressure of a verdazyl radical crystal has been studied. Computational modelling revealed changes in electronic and magnetic properties as a result of a structural phase transition.The response of the 1,5‐tolyl‐3‐phenyl‐6‐oxo‐verdazyl radical (pTolOV) to pressure in the crystalline state has been ...
