METHOD AND MEANS FOR CONTROLLING THE INTEGRITY OF AN ELECTRIC RESISTANCE

Device (C) for controlling the integrity of one or more insulating layers (13) of a multiple insulation resistance (10), wherein said one or more insulating layers (13) are consecutive layers (13) confined between the outermost (11) and the innermost (12) sheaths thereof. Said control device (C) is...

Beschreibung
Zusammenfassung:	Device (C) for controlling the integrity of one or more insulating layers (13) of a multiple insulation resistance (10), wherein said one or more insulating layers (13) are consecutive layers (13) confined between the outermost (11) and the innermost (12) sheaths thereof. Said control device (C) is provided with an electrical circuit (20. a; 20. b; 20. c; 20.d) having connection points (A, B) with said outermost and innermost sheaths (11, 12) and, in series with said connection points (A, B), a low voltage current generator (22) and indirect (23) and/or direct (R; 26; 30) disconnecting means of the supply of said multiple insulation resistance (10). Said current generator (22) is suitable for generating, in the case of degradation of the dielectric power of the one or more consecutive insulating layers (13), an electrical power and a short-circuit current (Ice) sufficient for activating said indirect (23) and/or direct (R; 26; 30) disconnecting means.
