Abstract
Method for the continuous insulation monitoring of an electrical conductor arrangement (12) with an active conductor (3) and a conductor structure (14) electrically insulated from the active conductor (3), wherein the quality of the conductor arrangement (12) as well as the arrangement of the active conductor (3) and the conductor structure (14) is such that almost identical propagation conditions for the active conductor (3) and the conductor structure (14) apply to a current flow against ground (E), wherein an insulation resistance measurement is being carried out, wherein an insulation monitoring unit (20) is connected between the conductor structure (14) and ground (E), which superimposes a measurement voltage onto the electrical conductor arrangement (12), which generates a measurement current proportionally to the insulation resistance of the conductor arrangement (12), which is acquired in the insulation resistance measurement unit (20) and evaluated.
