<p>A system for cooling a power transmission system comprising a cable carrying a current, the system comprising: a cooling device; a power supply system arranged to extract a power fraction from the cable and to supply the cooling device with said power fraction; a control unit configured to control the amount of the extracted power fraction responsive to a parameter of the power transported in the cable, so that when the parameter is higher than a threshold, the power fraction is equal to a first value depending on the power carried in the cable through a first function; and when the parameter is lower than the threshold, the power fraction is equal to a second value depending on the power carried in the cable through a second function, the second function corresponding to the first function multiplied by a factor k, k being higher than 0 and lower than 1.</p> |
