This Position reports to:

Normally, instabilities in electrical arcs are seen as a defect (e.g., welding, fusion plasma reactors). However, in electrical switchgear, instability is a feature. Different types of instabilities in electrical arcs (e.g., kink, helical, and sausage) can be used to extinguish electrical arcs. The thesis aims to investigate how these instabilities accelerate arc extinction in DC circuit interrupters.
