Hello,
I am displaying my Tesla Coil in a giant room where there will be dozens
of other people displaying their creations. Alot of the stuff there will
be sensitive electronics. Should I put my Tesla Coil in a Faraday Cage
and if so what type do you recommend? Also, since my coil is going to be
indoors should I be concerned about ozone?
I have a classic type coil made up of 2 - 9,000-volt neon sign
transformers. It is about 48" tall and emits about 24" long arcs.
be aware that a cage is not a "shield": It will prevent sparks from
going past the cage, but it will not eliminate RF interference and
transients from getting out.
If I wanted to make sure that nobody got "touched" by a spark, then I'd
set up a sort of curtain of something like chicken wire. It can be the
biggest size (2", I think it's called). You could probably also use
rectangular wire mesh (like used for reinforcing concrete)
Are you going to be responsible if someone claims that their sensitive
electronics was damaged? Think carefully: as noted above a cage will
prevent direct strikes, but doesn't really reduce the electric or
magnetic field transients very much.
