... e.g. when converting "1-EHVHV-mixed-all-0-no_sw".

Within the routine, the line types get converted and result in pairs of types with similiar / equal attributes, but different rated voltages. Specifically, there are types, with the same electrical parameters, one for 220 kV rated voltage and one for 380 kV.

However, unfortunately, when converting the lines themselves, the wrong type gets select. Let there be a line between two 220 kV-nodes, then a 380 kV line type is selected, although a 220 kV type is available.

Please do research on how that error can occur and try to develop a solution.

Addition on this issue: Regarding the above mentioned SimBench-Code, at least the line with id "EHV Line 610" between the nodes "EHV Bus 1701" and "EHV Bus 1901" (both have 220 kV as rated voltage) is affected. In the conversion, I ran, it evaluated to line type "LineType_1" with the given parameters:
iMax = 1300.0 A
vRated = 380.0 kV
b = 3.61283 nS
g = 0.0 nS
r = 0.08 Ohm
x = 0.32 Ohm
