Striking difference in topload discharge depending on type of driver.

Interesting theory. Thank you. I will certainly investigate it once I finish working my HV diff. probe.

You should be commended for making interesting experiments on TC discharges! It is difficult and almost impossible to accurately measure top volts on the secondary , but good comparison between two cases can be made simply by considering secondary bottom peak currents (since frequencies and voltage profiles are pretty close).If you can adjust SGTC to run in a single shot (or very low BPS) mode and observe toroid sparks breakout in dark do such experiment too.

Hi, The smooth,clean voltage rise in the case of DRSSTC hasn't got much to do with the spark type difference you observe.It has more to do with time to the voltage peak which is much shorter for SGTC and the energy can't be dissipated fast enough by a single spark vertical spark (spark needs time to grow too).Probably the peak voltage is lower for DRSSTC as well (if you apply same power and BPS in both cases).This you may see by scoping secondary bottom current amplitudes.

Nice ;) Thumbs up :D Alex

nice!

Just judging by appearance and power input, I'd say that the SGTC produces in the 300-400KV range, while the SSTC probably not even reaches 100 KV. You can get a reasonable estimate of the voltage if you replace Mr.Tesla with a smooth metal ball. If you can get visible effects (corona/streamers) from a 1.3 cm diameter ball, you are at roughly 100 KV. This is a linear function, so 2.6 cm would be 200 KV etc. To increase the reliability you should use a very smooth top-load as well. There are a number of reasons for this difference, this space is too small for a good and complete explanation. (dV/dt, Earth E-field, Atmospheric E-field, heat, charge density)

imagine the QRM lol

sgtc has more dv dt.
