Experimental validation of ultra-shortened 3D finite element electromagnetic modeling of three-core armored cables at power frequency
(Elsevier, 2022-02)
Due to recent advances, the numerical analysis of submarine three-core armored cables can nowadays be developed through the finite element method (FEM) in a small slice of the cable. This strongly reduces the computational ...
