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.
Cable condition monitoring system.
A cable is simply made of a conductor wrapped in one or more layers of insulation material.
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.
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.
Jubatus offers a range of condition monitoring systems from our partners in germany and italy.
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.
With conventional systems a sensor is needed for each point of interest.
This helps optimize transmission and distribution networks and reduces costly and unnecessary operational costs and asset downtime.
An ap sensing distributed acoustic sensing das system is monitoring a 6 km high voltage power cable in germany.
