Condition Monitoring and Early Fault Detection for Power Cables
A power cable failure not only incurs high costs but also damages a company’s reputation. Solutions for early detection of faults and disturbances therefore minimize downtime and prevent costly repairs. Continuous condition monitoring captures not only electrical states but also anomalies along the cable route – enabling targeted optimization of maintenance strategies instead of relying on rigid, fixed intervals. This increases the reliability of power grids – particularly for critical infrastructure such as railway power systems or offshore wind farms

The WITT WB-CM3 monitors the insulation between the shield or conductor and an earthing point and signals the event via potential-free signaling contacts. Measurement data can also be transferred to third-party systems.

The fully analog CM200 is used to detect changes between two potentials. A typical application is monitoring shields for insulation faults or interruptions.
The operating status is indicated by LEDs or potential-free signal contacts. The CM 200 operates without auxiliary power.

The WITT WB-CM 7 monitors the insulation between the conductor and the shield, and between the shield and an earth point, such as water or track earth. It detects the location of the fault and reports the event to third-party systems via a log.

The WB-CM4 continuously monitors power cables and return conductors in high-voltage direct current systems up to 1,500 V DC and detects insulation faults and shield breaks at an early stage – before they lead to operational downtime or safety risks. It measures the resistance between the conductor and the shield, as well as between the shield and earth, monitors both for breaks and reports faults via potential-free relay contacts. With the option to add an additional measurement channel (WB-CM41) as well as sensors for temperature, humidity and motion, the system is suitable for light rail systems, charging infrastructure, battery buffer systems and solar installations.

The CM 400 is a self-resetting cable monitoring device for railway applications. It detects faults in DC cables, particularly within the catenary and power supply infrastructure of electrified railway lines, thereby contributing to the operational safety and availability of the cable systems.
