why are you interested in losses, that _have already took place_ at
transfer? you have a Isec (pk) value, and this value determines energy
in secondary, having already took these losses into account.
2E = Ls * (Isec (pk))^2
after quarter of period it transforms into 1.9 MV - without losses;
with them - a little bit less, but not 1.5 MV, coz this (as it was
mentioned above) mean unreal losses.
