MONITORING SYSTEM FOR AN ELECTRIC POWER CABLE, ELECTRIC POWER CABLE FOR SUCH A MONITORING SYSTEM AND METHOD FOR MONITORING AN ELECTRIC POWER CABLE WITH THE AID OF SUCH A MONITORING SYSTEM

摘要

The monitoring system for electric cables (2), in particular for earthing cables or power cables for railway installations comprising said power cable (2) comprising a cable core (4) and a cable sheath (8). is formed in the power cable (2), a plurality of monitoring conductor (14) is integrated, which are electrically connected to each other, so that a monitoring section (20) having a cable individual electric characteristic between two signal terminals (26) of the monitoring section (20). thereby are used for different power cable (2) different cable individual electric characteristics, particularly resistors (R1, R2) is set. Thereby, a stealing of such power cable (2) is more difficult because this is detected even in a bridging of the signal conductor (14) and thus an alarm signal can be output.
