6284	When condition with dae mode	marianne.saugier@…	Andreas Heuermann	"Such an example works fine with ida but not anymore when adding the dae mode (the variable U stays constant equals to 1):

Real U(start = 1);
equation
when time >1 then
  U = 0.8;
end when;

We are working on an electrical test system and we need the dae mode so that we can simulate within acceptable time, but we also need to simulate the tapChanger behavior, which is impossible in dae mode because the tap stays constant.

This problem can also be observed with PowerGrids/Electrical/Tests test case ""TestTransformerWithTapChangerInterval"": when adding the dae mode, the tap doesn't move anymore.
