Wirescan will during the fall of 2015 perform a LIRA test on one high voltage and one medium voltage subsea power cables on the western coast of Norway.
The high voltage cables were tested by LIRA in 2012, and the scope of this year’s campaign is to compare new measurements with the previous references, to identify any changes in the cables impedance. If the two tests are identical, it will give the cable owner confidence that no damage or weak points have developing in the cable, – that potentially could lead to a break down.
A second medium voltage cable will be tested for the first time to perform a cable condition assessment.
The LIRA cable diagnostic system is a non-destructive test for cable condition assessment, cable condition monitoring and cable fault location.
