Abstract (en)

[origin: US2013100558A1] The method comprising displacing the formed electric arc towards an electrode located in an intermediate position between both main electrodes; a separating the formed electric arc into two secondary electric arcs, a semiconductor switch, normally open, connecting the intermediate electrode to one of the main electrodes; closing the semiconductor switch in order to extinguish the secondary electric arc between both electrodes connected by the semiconductor switch; opening the semiconductor switch in order to extinguish the other secondary electric arc. The disclosure further relates to a protection method and a protection device, notably a protection device specially designed for applying the method.
