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. 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. Condition monitoring for power cables often entails a manual periodic inspection process. 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. 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. 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. Jubatus offers a range of condition monitoring systems from our partners in germany and italy. This paper presents the research and development of an integrated high voltage hv power cable condition monitoring and fault localization system.

For applications spanning large areas and longer distances these solutions become over complicated bulky unreliable and costly to maintain.
