Pardon me for asking, but what in the world are you talking about? The best I can figure is that this new system is impractical to build due to the large value inductors and capacitors required. Obviously input VA would play a factor in choosing the appropriate values of L & C; correct? Do you have any photographs of your coil? I heard a while back that someone on the list was offering 1H air-wound cores very inexpensively. I am anxious to find out more about your theory. Please advise on your progress. Sincerely, Hank -----Original Message----- From: tesla-bounces@xxxxxxxxxx [mailto:tesla-bounces@xxxxxxxxxx] On Behalf Of Harvey Norris Sent: Friday, May 22, 2009 8:54 PM To: tesla@xxxxxxxxxx Subject: [TCML] 60 Hz Binary Resonant Primary Design A new sort of "quenched" arc gap is again brought up, to describe the secondary ballasting system, and for considerations of probable actions for primary ballasting. Inductive air core secondary reactive balancing of nameplate 150 nf values has been achieved in duplicate, or in a binary fashion. To describe the arc gap may sound initially confusing. For the system worked out here it must necessarily use large C values for 60 Hz. It is best understood as a single Marx gap set-up. Two capacities are charged up oppositely and discharged from the opposite ends not connected to the voltage supply. However reactively balanced air core large induction coils are in parallel to this sort of arc gap. When the arc gap is shorted the secondary voltage process is basically "self ballasted for arc quenching purposes" where its conduction levels at short can be measured. When two capacities being charged oppositely in parallel are connected at midpt short, the new resultant capacity is half the amount now in series. The same principle can be shown inversely for the inductive reactive counterpart especially with mutual inductance considerations for tuning. It can be shown that when two 180 phased series resonant voltage rises are shorted at their midpoints, the current across that midpoint path is then reactively limited to its pathways of identical reactance in series on either side of the midpoint path. However what may not be readily understood or addressed as a potential arc gap improvement of that mechanism is the fact that when the inductive reactive midpoint path shares the same lines as the capacitive reactive midpoint path, because each current is 180 out of phase, the new current limitation across that path becomes double of either side alone. To address this issue, each side must be isolated from the other in which case the measurement becomes two 150 nf values in series ~ 75 nf/ balanced by two 65 H coil formations in series with mutual inductance to tune by. In this specific case here the 60 hz parallel tank factor appears to have an acting Q factor of 6. What this means of course is that a great gain of efficiency stands to be gained by the power factor correction afforded by these large coils. What this means in practicality is that a pole pig transformer on arc gap short will act as if it is charging a 75/6 = 12.5 nf, but the actual capacity being charged is 75 nf. However the peculiarities of this binary resonant design are are large draw before arc ignition whereby 150 nf in parallel being charged equates to a huge 300 nf draw, so the scheme seems unworkable with NST's. It then becomes problematic to how such a charging sytem should be employed with primaries. I believe the best approach would be to put the arc gap midway along the primaries pathway. A considerable amount of reduction of primary inductance seems necessary since the C values are comparatively high. However the paradox in this scheme is the ungodly high inductances themselves employed in the secondary C power factor corrections and how they might be interacted with the engaging primary inductances themselves.
