Hi Steve,
The top turn of Tesla's Colorado Springs Coil was set up higher and
basically acted as a corona ring. By being set up higher in space it
created a large high voltage field area that reduced the voltage
stresses on the top of the primary* and prevented arching.
Tesla originally had a conical primary coil (CS notes pg. 221) that
probably had all kinds of nasty arcing problems so he rebuilt it with
the much better cylindrical primary (CS notes pg. 203) that he used in
most of the later real experiments. The top turn was deliberate
designed into that for corona protection. Tesla used the twisted wire
instead of say a thick metal tube like Wysock did since Tesla did not
have McMaster-Carr. :D

Folks,
Found this in a file I saved from Chip's List (12/29/1999 8:10 PM)
Does anyone have a clue to what Bill was talking about?

*** TESLA SECRET***
Tesla's (final configuration) was with a secondary
(master oscillator driver coil,) that was cylindrical and 51
feet in diameter (approximately.) Also, the top turn as
seen on top of this "fence" was not, as most folks think, (including
myself,) a grounded open loop turn. It was used for purposes
yet to be disclosed! I am referring to the twisted pair turn on the
clear glass insulators, mounted on top of every upright vertical
post, that forms the coil form for the secondary.
Regards,
Bill Wysock.
