@SanPen, @alexblancoeroots there are additional issues with the short-circuit routine for mid-line faults. When a dummy bus is added, the number of buses increases by 1, but the self.pf_results.voltage vector...

Yeah, that's the approach I used through the VeraGridEngine. It could make sense to send the pf_results to the split_branch() function and append the voltage of the dummy bus.

I implemented a somewhat different approach. Instead of modifying the numerical circuit, I modified the grid, as it seemed easier to modify and conduct a power flow study. The `split_branch()`...
