Re: ref: the physics of a neo...
Regarding your comments concerning PK's...
IMHO, the biggest problem with PK's is the metal shell. They are nothing but
trouble, and it often turns out that I get better results with just a wire
running out of the PK to a doubleback. Not very elegant but in reality this
turns out to be less troublesome. If someone would create a PK with a
non-metallic shell, that would represent a significant improvement. The shell
is nothing but a zero potential ground surface that gives the HV a proximate
place to arc over to, eventually through the pyrex cracking the glass. That
is one of the very most dangerous situations. Using ENT and a totally
non-metallic PK would represent a major improvement.
In many of my residential installations (dare I say this, just because it's
true?) which have been actually zero failure for over 5 years I find that
actually using only an ENT conduit emerging plain with no PK through a
sheetrock wall with a HV wire coming out to a doubleback incredibly works
just fine, there is never any danger because there's no ground surface to arc
to.
SO, there are many, many situations where PK's are unnecessary in interior
locations where ENT is used. This is, of course, IMHO, too heretical for
those traditionalists who shock easily and for those impressionable newcomers
that "ought to learn the traditional way".<g> (I don't frankly give a BS
about that, I work for results, and I get them.) I really don't think that a
lot of neon is well understood yet and I have definitely found some of it
can be immeasurably simplified.
BY THE WAY!!!
For those of you that haven't tried it, neon whites are great cove lighting
for general purpose lighting in residences or commercial coves. Is anyone
interested in this subject? Have done a lot of great coves and carved glass
edge lighting in residences. I know this is going to open a can of worms, but
it's worth it.
