It would be intersting to see how arc length would improve if you lift the coil up a bit off the ground, and increase the BPS rate.Coupling is also pretty important on big coils... Have you experimented with increasing the coupling at all? Carlos On 2015-01-02 08:13, vam@xxxxxxxxx wrote:You got my message spot on Carlos. The coil produces constant streamers about 20- 23 feet, or 6 - 7 meters. It's very impressive. But i did make a coil with 1 m winding length before, producing 3 meter sparks at 20 kw. so i expected around 10 meters with this set up. but 7 seems the max.Big machines like this are typically less efficient than there smaller brothers and sisters. I have not taken the time to run the numbers on the info you provided, but if the system is well balanced and in tune and pulling 40kva, I would expect to see 20-25 foot long arcs at minimum. The height of the coil will also be a limiting factor to some degree... I assume from your question that you are not happy with the performance or it did not meet your expectations?

It's total height is 5 meters. the donut is 2,60 by 60 cm. the coil is 65 cm dia with 1200 turns of 2.5^2mm installation wire. about 3.6 meter winding length. Cap, DR resonance 100nF, 80kv 4 in parallel. We feed it with a 180kva 10kv yz5 transformer. Rectify the lot to 16kv. ballast ensures 32kv on the cap. at 200 bps we draw 50-60 amps per fase. so roughly 40 kw. Max bps is 700. Now the question. What kind of spark length should be possible from this coil?
