There seems to be a dependency for 50Hz Sine transformers - such that the less ampere turns on secondary the less actual output power . . . no matter the copper diameter !
The TF.2 has 2-le - and the TF.1 has 3-ple in parallel secondary winding from 01..0.08mm wire - e.g. - a lot of amp.-turns.
so here what we got
and a figure
note :: for the TF.1 is shown L.1.Before some 29(H) and .After 45(H) -- there's another experiment listing the values for the original NiMH charger's TF as R.i = 1251(Ω) and L.i = 47.5(H) , R.ii.YR (yellow,red wire , center tapped , total) = 2.4(Ω) , 9.11(V) - & - R.ii.BB (blue,blue , total) = 54.3(Ω) , 28.8(V) - but there's no much other data - i guess the ~AC.peak! voltages were required at the time --- so the table has data for TF.1 from the more complete experiment . . .if we multiply the 29.3(H) with Pi/2 we get 46.1(H) -- so i guess there's a current measurement peculiarity involved -- as Z = U/I = U.AVG / I.AVG , I.AVG = I.MAX·(2/π) -- or -- the prev. more precise Z.correct = Z·(π/2) → L.i = 46.4(H) , L.ii.YR = [P.i=P.ii=U².x/Z.x] = 44.546(mH) -- !!! however it does not much affect the DC(direct current) test values that are compared here
The TF.2 has 2-le - and the TF.1 has 3-ple in parallel secondary winding from 01..0.08mm wire - e.g. - a lot of amp.-turns.
