This updated method makes it possible to model the electrical resistance of the conductor independent on whether automatic or user defined conductor material characteristics (temperature coefficient, thermal resistivity, and specific heat capacity) are selected. Three different ways of electrical resistance input for conductors are now possible:
This will take the DC resistance at 20°C for the corresponding cross-section (mm²) from the IEC 60228 standard or different American standards for AWG/kcmil as described in the documentation.
Directly specify an electrical DC resistance at 20°C. Input in Ω/km.
Calculate the value based on the conductor area and the specific electrical resistivity at 20°C provided in Ω.m.
