| Variac | Powerstat 144v 22A |
| Bus Wiring | #10 AWG, PVC insulation, and ring terminals at ends |
| High Voltage Supply | 12Kv, 60ma NST running 14.4Kv @ 77.2ma - 1111.69va Is being taken apart to get more current from it. |
| Safty Gap | N/A - Shorted out throught wood on a run |
| Chokes | N/A - On board with safty gap so had to be taked off also |
| Spark Gap | Static vacuum gap with 10(using 9) 1" X 4" electrodes in 6" PVC 0.027" per gap 0.243" total (using 0.216"). vacuum motor not hooked up yet |
| Caps | Total .02126µF 2 banks of 2 10.5Kv .02µF rolled poly caps in series for .01µF oiled bank measures .01089µF inline dry bank measures .01037µF dry bank finally gave out at the increased voltage |
| Primary | Flat "pancake" spiral, 7 turns with I.D. of 6", .25" tubing, .25" spacing has been taken apart to make a primary for my 3" coil |
| Secondary | 4.5" X 20.75", #24 magnet wire wrapped on .25" thick PVC |
| Discharge Terminal | 2" X 6" toroid made from 4 steel ducting elbows I got my new 2.75" X 24" ready to go for when I build a new primary now |
| Ground System | 10' of #3/0 AWG connected to drain pipe in basment |
| Max spark to date | 10 or more bright 22" long streamers |
| Notes & Other Info | The output is better then when I had used three 30mA 12Kv's. Before I
couldn't get any breakout from a toroid. I had just used the copper tubing that
I placed around the top as a discharge terminal. I got fewer less powerful
streamers then, but about the same length. This prolbably has something
to do with it close to being in tune now. My next primary will have a cut out
for the secondary to adjust the coupling a little. I also hope to have the
vacuum motor ready to hook up soon. Just gotta work out the power control. |
