Subject: effects of spacing secondary windings
Hello all,
I'd like to tap into the knowledge of all you theorists out there,
and ask a question about a topic recently in discussion here: spacing the
windings of the secondary with an inert spacer (eg. fishing line) to prevent
breakdown.
Common intuition tells me that a 21" coil wound with 1000 turns of
magnet wire (tightly) is not the same coil as a 42" wound with the same 1000
turns with one diameter between each turn, right?
What is the effect (if you think there's any) of winding a secondary
in this fashion on the frequency, inductance, self-c, etc? I'm presuming
such winding renders programs like wintesla useless?!
I'm starting construction of a fairly large coil, and I want to space
the windings; however, obviously, whether or not I do is going to make a big
difference in the diameter of wire I'll be using - my secondary is going to be
nearly four feet high, and about 12 inches in diameter (using 10 kVA PP for
supply).... 8-)
Thanks in advance, and happy coiling to all.
Clay.
