The National Arc fault Research Center (NARC) which belongs to the Technischen Universität Dresden concerns about the examination of high current serial and parallel fault arcs in electrical low voltage grid in projects with partners from the industry as well as from sciences.
> Weitere Informationen zum NARC als FlyerIf a fault arc ignites in a high power electrical system there is a high harzard potential for the electrical system involed but also for the personnel. As a result the involed equiptment gets destroyed and in this case the power blackout of the electrical energy supply is the consequence.
The reasons for the appearance of fault arcs reaches from a incorrect rating of the electrical equipment up to animals reaching in the electrical system. But, one of the main reasons are wrong or unwarily done maintenance and operating work.
To ignite the fault arc a thin copper wire is short-circuiting the electrodes
Experiments wirh fuses that show diffrent typs of time behaviour
Flying firebrands from a fault arc
Wir halten Fachvorträge zum spannenden Thema der Lichtbögen
The measurement of current and voltage with a high sample rate
Even if our test bench is placed outside wind and wether do not affect the workshop
We do offer individual workshops and demonstrations and do also conduct research in the field of serial and parallel fault arcs!
