Hi, I am trying to model a 110kV high voltage cable in Maxwell so that when I set a current value in the main conductor, I get the temperature value to which the cable has heated up. More specifically, I want to get the current carrying capacity of the cable.I know that I need to combine the analysis with Icepak. I have created a 3D model of the cable that is 10cm long to reduce the number of mesh elements, which is problematic to generate anyway. I also have a region which, where the ‘cut’ edges of the cable are, meets the surface of the cable. On the perimeter it is offset 100% from the cable surface. I considered that the eddy current type of solution would be correct. I’m wondering how to set the excitations and boundaries? If I only want to analyse this 10cm slice, how do I ask for the current path and what to set on the “cut” edges of the cable?<\/p>\n
