this means that the optional value "x0x_min" is missing from the element table net.ext_grid
pandapower requires additional (optional) parameters to be added in order to execute a short-circuit calculation

Issue
hi sir, here i am sharing the error which i have got during the execution for calculating 1ph sc calculation please suggest me to address this issue KeyError Traceback (most recent call last) File ~\anaconda3\lib\site-packages\pandas\core\indexes\base.py:3802, in Index.get_loc(self, key, method, tolerance) 3801 try: -> 3802 return self._engine.get_loc(casted_key) 3803 except KeyError as err:

The above exception was the direct cause of the following exception:
