Finite Element Analysis for Cable Rating Calculations

In recent years there has been increased interest in using the Finite Element Method (FEM) for the calculation of the current rating (often referred to as the "ampacity") of power cables. Although more traditional methods (chiefly analytical calculations using IEC 60287) are still the most common practice, the use of FEM for specific current rating calculations has increased in the last years, mainly pushed by a higher accessibility of calculation engines (be it in terms of required computing power, or necessary expertise).
