Sheared magnetospheric plasma flows and discrete auroral arcs: a quasi-static coupling model [PDF]
Annales Geophysicae, 2007 We consider sheared flows in magnetospheric boundary layers of tangential discontinuity type, forming a structure that is embedded in a large-scale convergent perpendicular electric field. We construct a kinetic model that couples the magnetospheric

Energy and flux variations across thin auroral arcs [PDF]
Annales Geophysicae, 2011 Two discrete auroral arc filaments, with widths of less than 1 km, have been analysed using multi-station, multi-monochromatic optical observations from small and medium field-of-view imagers and the EISCAT radar.

Monopolar and bipolar auroral electric fields and their effects [PDF]
Annales Geophysicae, 2010 Most of the high-altitude auroral electric fields observed by CLUSTER can be classified into monopolar and bipolar structures. The observations associate monopolar electric fields with polar cap boundary arcs, while bipolar fields tend to be linked to

Research on the arcing horn with active arc extinguishing function for HVDC grounding electrode line
IET Generation, Transmission & Distribution, 2023 The grounding electrode line is an important part of the Ultra high voltage direct current (UHVDC) transmission system. It acts as the channel to conduct the unbalanced current and the grounding current.The arcing horn consists of a pair of electrodes ...

Dataset of measured and commented pantograph electric arcs in DC railways
Data in Brief, 2020 DC railways are characterized by particularly intense arcing caused by pantograph detachment, due to the large current intensity and the general implementation of onboard resonant filters, whose transient response is triggered by electric transients ...
