In PSCAD transmission line model, we are not able to define tower footing resistance in 'transmission line segment' component. So, my question is in regards to PSCAD only.
- in lightning studies, we can model a tower and its footing resistance, which is outside the 'transmission line segment' component. Howevevr, this can be done only for few tower spans.
-for long lines, if we do not eliminate OHGW, will it experience some grounding at every tower span i.e. 350 m. What will be the value of that grounding resistance?
