Can RESICALC or SUBCALC model underground cables?
The current versions of RESICALC and SUBCALC have no specific tools for modeling underground cables such as pipe-type cables and cables with concentric neutrals. The existing tools are primarily designed to model overhead lines but have the flexibility to model just about any line above or below the ground. When modeling underground cables, you should keep in mind that you will most likely get magnetic fields that are over estimated near the cables because the program does not calculate induced currents on pipes and thus will not attenuate the fields.
