Tom,

I will put aside all comments that smell of Napoleonic Disorder. However I
will answer you about the
transformer "conjugate match".

I will remind you for the "n" th. time that these words have been used as a
comparative point for those that do not understand the process of nullifying
a reactance with one with an opposite sign.

To be more concise and to clarify this issue once and for all:

Any device, including a power transformer has a definite and measurable
reactance at it's operating frequency. In the case of an 220VAC transformer
this reactance has two components, one inductive - from the winding it
self - and one capacitative created form the internal inter-thread and coil
to core capacitance. All losses in a transformer, including leakage, are
related to these rectances. A good engineer will always attempt to reduce
them as it ultimately translates in heat.

And here I go again!

Much more like the conjugate match in an antenna tuner, the smart engineer
will at least attempt to compute and then test the inverse reactance
networks needed to nullify the ones in the transformer!
If this is possible as some practical issues can impede this effort.
Efficiency then is improved, heat is diminished and al-in-all you have a
sound electrical design!


I hope this will clarify and close this issue and help you design your next
transformer.

And Tom... I propose a truce ... I will not comment on your messages no
matter what they contain ...
I will ask you to do the same about mine. OK?

Alex
