Hello everybody,
I'm modelling a HV cable in a tunnel and I'd like to know how I can model the typology of the sheath (single point, two point or cross earthing). For example if we take the COMSOL Submarine Cable file, how can I define how the sheath is connected to the earth? What if I'd like to simulating a cable that has not the sheath connected to the earth?
For my simulation, I need to find the capacitance between the sheath and the earth Furthermore, if I decide that there is some passive elements in the connection sheath-earth, how can I model the system?
Some suggestions or tips?
Thank you very much to everyone!
