Dear lectors, in this post I show the results of the 3D simulation with variable axial spacing between conductors within the cable (S) and conductor diameter (d) of the inductance L per core of a 3-core cable or of three single-core cables comprises two parts, the self-inductance of the conductor and the mutual inductance with other cores, given by:

L = K + 0.2 loge (2D/d)
