Cable Condition Monitoring System

A cable is simply made of a conductor wrapped in one or more layers of insulation material.

Cable condition monitoring system.

A key feature of das is the ability to immediately detect and locate cable faults. Distributed temperature sensing has applications in both monitoring by alerting users to any critical faults in networks but also sensing of abnormal conditions ranging from fire detection to cable security. An ap sensing distributed acoustic sensing das system is monitoring a 6 km high voltage power cable in germany. For applications spanning large areas and longer distances these solutions become over complicated bulky unreliable and costly to maintain.

Condition monitoring for power cables often entails a manual periodic inspection process. Jubatus offers a range of condition monitoring systems from our partners in germany and italy. The system consists of the functionalities of online dielectric loss dl monitoring outer sheath and earthing system condition monitoring and a rapid fault localization system all based on monitoring of cable sheath currents. With conventional systems a sensor is needed for each point of interest.

While testing conductors connectors and end devices is performed in response to specific operational problems cable condition monitoring is performed to identify degradation in cable insulation material and for cable aging assessment and remaining useful life prediction.
