Testing EHV secondary arcs

2001 IEEE Porto Power Tech Proceedings (Cat. No.01EX502), 2002
The protection of the environment requires compact EHV tower constructions. This trend results in decreasing the clearances and phase-to-phase distances. It is expected, that both the number of faults and the amplitude of the secondary arc current will grow in the future.

Characterization Experiments of Secondary Arcs on Solar Arrays: Secondary Arc Physical Parameters

Journal of Spacecraft and Rockets, 2014
Secondary arcs on solar arrays are a serious threat to the safety of spacecraft operation. Experiments to characterize secondary arcs are currently being conducted. In this study, the effect of external capacitance in the test circuit on the transition from a primary discharge to secondary is investigated.

Secondary arcing in space environment

2015 IEEE International Conference on Plasma Sciences (ICOPS), 2015
Secondary arc initiation in the electrical distribution (ED) of spacecrafts (SC) is much sensitive to the SC environment and a kind of primary discharge. Standard procedures on secondary arc tests imply electrostatic discharge (ESD) as an only source of arcing. However, the problem of secondary arcing is actual also in equipment where ESD has no chance

Secondary arc dynamics in a railgun bore

IEEE Transactions on Magnetics, 1999
We have conducted a series of experiments on the growth of secondary arcs in railgun bores. The experimental results indicate that the secondary arc grows bigger as the stored energy of the capacitor bank becomes higher and as the diameter of the railgun bore decreases.

A triggering mechanism for secondary arcs (railguns)

IEEE Transactions on Magnetics, 1993
It is postulated that there is local change in the magnetic field, associated with the rail joint connections, which causes a variation in the breech voltage and in the J*B force applied to the armature. Experimental data suggest that this change in force can trigger secondary arcs.

Secondary arc formation and evolution in railguns

1990 Plasma Science IEEE Conference Record - Abstracts, 1990
Summary form only given. A computational code based on simple models has been developed as an aid to understanding the complex physical processes which promote the formation of secondary arcs and control their evolution in plasma armature railguns.

Comparison of secondary arcs for reclosing applications

IEEE Transactions on Dielectrics and Electrical Insulation, 2017
This paper presents a comparison of secondary electric arcs behavior for reclosing applications. The main objective of the paper is to show the differences in secondary arcs during simulations, laboratory tests and real life events. These comparisons can help engineers develop adaptive reclosing algorithms and improve power system stability. A software
