Power Cable Health Monitoring Method
US Patent 12025568
Published July 2, 2024
Inventors: Alastair Bryan Godfrey, Fleet, Great Britain; and Chris D G Minto,
Hinckley, Great Britain
Assignee: Indeximate Ltd., Leicestershire, Great Britain
A power cable monitoring method which can be used to measure the
mechanical state of health of subsea power cables. This method uses the
magnetic properties of the load-bearing components of the power cable
and the current carried by the power cable to apply an alternating force to
itself. The only source of force from an alternating current in the cable
which is at the fundamental frequency (F0) of the electrical power originates
from magnetostriction of the steel armor. This force is predominantly axial.
The strength of the F0 signal is used as an indicator of strain in the cable,
where changes over time can be used to monitor the mechanical integrity of
the cable structure. 2F0 signals are complex sums of axial, radial and
tangential forces which are difficult to analyze. The 2F0 signal is therefore
predominantly used to normalize the F0 signal.
