AI prediction of underground cable and joint faults
HK Electric put AI cable-fault prediction into maintenance use in 2022
Problem
Underground cables faced damage from water ingress and construction as well as ageing. Fault investigation could require engineers to excavate and inspect a long cable section.
Approach
HK Electric worked with a local university to develop AI for assessing cable condition. The system entered use in 2022 and analysed historical test data to estimate fault risks in cables and joints. Engineers used the assessments to plan testing and maintenance.
Results
No published figures
Takeaway
The AI supplemented an existing cable-health programme. The programme's wider reduction in faults cannot be attributed to the AI alone.
