Arrangement for monitoring electric devices on stray light arcs

摘要: The invention concerns an arrangement for monitoring electrical equipment the emergence of accidental arcs. object is to more reliably recognize occurrence arc on lines, cables and/or contact sites or in devices than has been possible with previously known solutions. proposed comprises at least one conductor, which connects devices, subassemblies circuit components piece another, light guide optical fiber guides arising formation optical/electrical transformer, as well a and evaluating unit electrically connected transformer. envelops wire cores above-mentioned conductor thus simultaneously forms insulation line shielding cable.
