in pypsa the transformer reactances are in p.u. values. But the base power is not 1 MVA as calculated internally for all other components but the transformer specific installed power (s_nom). Therefore I think we have to change this line accordingly to:
(br_x/100)*rate_a

Whereever else transformer are added to the system in powerd-data/egon-data or eTraGo we should check that it is handled the same.

@ClaraBuettner do you agree? Or did I get s.th. wrong?
