RE: Calculating E-Field of SSTC or Tesla Coil

Terry -

There appears to be a problem with E-Tesla6. The program is showing an
incorrect Fres when compared to TSSP and JHCTES. This is due to the Cpf
being too large.

Bare secondary coil is isolated in center of room
Ceiling and walls 300"
Pri and sec windings at 200"
No surroundings effect

                     TSSP     JHCTES       E-Tesla6

Fres KHz  about     150      149.71        139.91

C pf                ---       13.30         16.38

Sec Ind mh          ---       84.97         84.97

When the capacitance effects of the surroundings are taken into
consideration (ceiling and walls = 100) the C pf should decrease and the
Fres should increase???

Hi Dan,

E-Tesla6 can calculate x/y arrays of numbers that can be imported into
Excel or MathCad.  See the readme file and the other site:

http://hot-streamer-dot-com/TeslaCoils/Programs/E-Tesla6.zip

http://hot-streamer-dot-com/andrewb/models/models.htm

The program is really to find Fo, but we have had great fun with the data
that can be plotted from the array work files.

Cheers,

          Terry
