Energy and flux variations across thin auroral arcs [PDF]
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]
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
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
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 ...

Sheared magnetospheric plasma flows and discrete auroral arcs: a quasi-static coupling model [PDF]
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

Radar observations in the vicinity of pre-noon auroral arcs [PDF]
A combination of EISCAT incoherent scatter radar measurements, optical and magnetometer data is used to study the plasma in and around pre-noon structured precipitation and auroral arcs.
