Description
Summary:AbstractThis paper presents the finite element electrothermal analysis done on an industry standard Kevlar armored subsea power cable to determine the cable overload and short circuit ampacities up to 256 times the continuous current rating. It is identified that the subsea cable could withstand 1.5 times and 256 times the rated current for a period of 17 min and 4.8 ms, respectively. The ampacity correction factors for operation in the water medium for a range of temperature and water flow velocities are also identified. The results presented in the form of equations shall serve as a guideline for determining the overload and short circuit protection settings of subsea power cables of similar construction.
