since i had to rate a lot of 'em - i changed my prev.
MMXIV-01-14 method - to a faster but not necessarily a better 1 the measurement schematic stays the same only the computations and what's being sampled a bit varies -- an example::

in short :: the
~AC-TEST -- returns Z
L1(Ω) and Voltage transfer ratio - which are used in computing the L
L2(mH) , U
L2(V)
AND I
L2.Chk(mA) , e.c. ...
the dynamic
~AC-TEST (under the [ Transformer Name : ] ) -- returns from U
L1(V) , U
L2(V) , R
TEST.N(Ω) --
/!\ /!\ something I
L2(mA) which are then checked against the
~AC-TEST based computed I
L2.Chk(mA)
from this it seems that the TF(transformer)'s power transfer is dependent on it's load -- see the R
BRIDGE(Ω) under the
—DC-TEST -- //// -- so you need to adjust the L
L2(mH) to match your circuit's average op.-g conditions (the previous method matched the average test range)
note::the "Characteristic String" is described in
HERE for more detail -- it's more meaningful inside the set of such for multiple TF-s -- has a comparative purpose.

MMXIV-09-08 note :: i in principle won't remove the below Bsh - the Blogger editor is (still - i guess) unpredictable (the 1-st impresion tends to stay - even more if there's no tendency to improvement throughout several . . . years ◄ such fixes a permanent attitude like below - i suggest you don't focus)
sub-note: Kuradi sita virvendus! Mõlemad - Blogger ja FF - nii koos kui eraldi -- üks kukub ära ja teine ei saa hakkama -- eriline utoopia on mingit asja siin üldse aretada kui debiilikud on töövahendeid üritanud teha (hea on kui see asi nüüd nii jääb nagu ta praegu paistab (kuradi idiootide maa - nahhui . . . persse!)) - no offence this is how i see it . . . i always wondered why people remove their blogs - i guess such may be a reason - if you try to do it (blog) too often - it eats the last of your nerves off . . .
Kõik , võimlemistund on tänaseks läbi XD (Vabakava Googli ja Tulirebasega XD XD XD &%!&&/!(&/¤#!%%/%¤ . . . Põrgu´!)
