Smart On-Line Health Assessment of Cable Terminations


Transmission grid failures can result in long outage periods with unacceptable societal impacts and negative economic consequences including significant loss of industry production and high not-delivered-energy costs (KILE). In the SmartACT project, an innovative and non-intrusive long-life sensor system for online condition assessment and monitoring will be developed and tested for installation inside 420 kV oil-filled cable terminations, which are the components most prone to failure. This novel sensor system will provide continuous feedback concerning the condition of the cable terminals, thus allowing for mitigation procedures to be enacted when necessary hence avoiding disruption of supply. The sensor system is expected to increase security of energy supply by assessing temperature, humidity, pressure, and partial discharges (PDs) combined with a new digitized machine-learning-assisted assessment methodology. SmartACT, therefore, addresses thematic priority area 3 in the ENERGIX work programme. Cooperation between the Norwegian TSO Statnett, Nexans Norway, SINTEF and NTNU is essential to meet the project goals.
