Hello,
I am currently building a medium size Tesla Coil. Here are some of the
specs:
NST - 15kV/30ma
Capacitor- 5.37 nF made from glass plates with heavy duty aluminum foil
on the inside and outside faces
Primary- 0.25" of flexible copper tubing
Secondary- 22 AWG enamel magnetic wire on 4" diameter PVC. Height- ???
I am thinking on 30". I've read that for a medium size Tesla Coil an
aspect ratio of 4.5:1 up to 5:1 is recommended. But then again, there
are no hard/fast rules.
According to WinTesla, 4"x30" with 22A WG wire yields 1090.53 turns but
the Aspect Ratio is 30/4 = 7.5. Would this be a problem?? At first we
were going to go with 22" or 23" in height (22/4 = 5.5) (23/4 = 5.75)
giving us around 800 turns, but I read that 1000-1400 turns tends to
produce better performance than lesser turns. The difference might be
10-20% spark length.
What do you recommend? Please advice. Your comments and suggestions will
be appreciated. Thank you.
Sincerely,
Ben Medina
