Abstract
A cooling system for cooling a power transmission system that includes a cable configured to carry a current corresponding to a transported electric power may include: a cooling device configured to remove heat from the power transmission system; a power supply system configured to extract a power fraction from the cable and configured to supply the cooling device with the power fraction; and a control unit configured to control an amount of the extracted power fraction in response to a parameter of the electric power. When the parameter is higher than a threshold, the extracted power fraction is equal to a first value that depends on the electric power carried in the cable through a first function. When the parameter is lower than the threshold, the extracted power fraction is equal to a second value that depends on the electric power carried in the cable through a second function.
