Cable Condition Monitoring System

With conventional systems a sensor is needed for each point of interest.

Cable condition monitoring system.

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. 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. An ap sensing distributed acoustic sensing das system is monitoring a 6 km high voltage power cable in germany. A key feature of das is the ability to immediately detect and locate cable faults.

For applications spanning large areas and longer distances these solutions become over complicated bulky unreliable and costly to maintain. This helps optimize transmission and distribution networks and reduces costly and unnecessary operational costs and asset downtime. Condition monitoring technique are presented along with a general discussion on the various properties of electric cable insulation that can be monitored to assess the condition of an electric cable and the dielectric integrity of cable insulation systems. Jubatus offers a range of condition monitoring systems from our partners in germany and italy.

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.
