VORRICHTUNG ZUR ÜBERWACHUNG DER ISOLATION UND / ODER KONTINUITÄT VON ZUMINDEST EINEM ELEKTRISCHEN KABEL UND ENTSPRECHENDES ÜBERWACHUNGSVERFAHREN

摘要

The invention relates to a device (10) for monitoring the insulation and/or continuity of an electric cable (12) comprising a plurality of electric wires, the device (10) comprising a measuring circuit (16) which can be connected to the electric wires, the measuring circuit (16) comprising: - a measuring stage (20) comprising a voltage generator (22); - a switching stage (25), which can be connected to the measuring stage (20) and is suitable for automatically and successively connecting each electric wire to the measuring circuit (16) and/or suitable for connecting the measuring circuit (16) to ground; - a stage for looping (28) the measuring circuit (16), said looping stage (28) being connectable, wire by wire, to the switching stage (25) and (28) being configured to operate automatically in at least one of two operating modes, i.e. an insulating or resistive mode, associated with monitoring insulation or continuity, respectively.
