RE: [TCML] Toroid height, What's best

["Dex Dexter" <dexterlabs@xxxxxxxxxxx>]

Compensation,if needed, for some change of
effective secondary circuit inductance.
Losses induced by proximity of the toroid to top
of secondary are negligible.
I read somewhere Q change based study,
with measurements,where they concluded that
these losses with various sizes of aluminium
toroids put just above top turn of secondary
where less than 3% of total input power.
If I rememeber correctly the losses became serious
only with steel objects used for topload,or with
frequencies well in Mhz range.

What the losses induced by proximity of the toroid
to the primary have to do with this?
I think not many build tesla coils with top toroid
just couple of inches above primary coil.
Maybe in some cases of mini Tesla coil :-)

A shorted turn is a loss, and there's no way to compensate for that.

However, the losses induced by proximity of the toroid to the primary are negligible, unless it's within just a couple of inches.
