RE: [TCML] 60 Hz Binary Resonant Primary Design

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi Harvey,

The way I have been going through meters lately, I need a collection like
yours. I see 9 in the pic. I realized inductive kickback was the culprit
after my second smoke job. I wish I could understand what the heck you are
doing! Seems interesting. Are you saying you can transmit power better than
a direct connection?
I always respect your posts. You lost me this time.
Jim Mora

I am talking about adapting a 60 hz series resonant system to that of a TC
primary arc gap. I have already built and found the secondary parameters for
a 250,000 hz NST functioning tesla coil. This uses 12 primary turns and 20
nf.

The first 60 hz resonant systems using a pair of 12 lb 23 gauge coils @ 140
ohms resistance, 1000 ohms inductive reactance used 3uf per side, a very
high C value when trying to incorporate A TC design, and a blown 440
transformer resulted when the arc gap accidently went open. Now the same
thing is done using 70 lb coils of 23 gauge wire; 840 ohms @ ~18,000 ohms
inductive reactance @ 60 hz.

Here are some former flicker postings on the 12 lb 60 hz binary resonant
pair: which is simply two inversely made series resonances whose
configurations can be changed to tuned primary and secondary.

I wound 140 ohms/ 23 gauge wire onto 3 inch ID smaller spools and arrived at
1000 ohms reactance(~ 2.4 H) @ 60 hz. Using a variac to keep the input below
120 volts to avoid overheating the wire, a pair of these can be inversely
series resonated using 3 uf for each side, where the tuning for the pair is
made according to the circumstances of their reactive amperage consumptions;
which in turn means they can be tuned for magnetic opposition or agreement
between the pair. This
procedure can produce a Q of an 11.5 fold voltage rise between a closely
spaced pair of the 12 lb coils. Next the input wires to one side are removed
after the circuit was tuned for a 1 inch separation. The former input wires
are shorted to make for a secondary air core transformer @ 60 hz,(not a high
frequency tesla coil. A smaller bathroom night light is given as that
secondaries load. Both of these systems in simultaneous operation are
pictured at both 60 volts and 90 volts input, which is the 1000 volt limit
for this volume of wire.

same load were directly wire connected to its source.

90 Volt input to 60 hz resonances, top pair produces 1000 volts between
them. Bottom air core secondary has input of .49A from primary,@ 435 volts
resonant voltage rise producing 135 volts secondary volts with bulb taking
35.7 ma from coil/cap circulation of 143.1 ma. Paradoxically the meter
showing the relative differences between the 435 volts and 135 volts on
secondary reads 0 volts. Apparently Isolated voltage rises cannot be
compared without making the autotransformer connection.

Definitely so, but with the larger 70 lb coils in series with two 12 lb
coils, values of 150 nf can be used with the pair. In the previous pics of
the 12 lb coils, I did not show the resonant rise of amperage factor, but
this will be shown with the larger coils in  flicker postings later. It is
noted that the large inductors are in series with each 150 nf value,
employing opposite polarity series resonant rises of voltage to charge the
capacities until the point of short by arc gap.
Upon short experienced with arc gap, the impedance of the entire circuit
seen by the supply increases by Q squared, and this is the first thing to be
measured; the acting resonant rise of amperage Q factor using all the C and
L values in parallel which shows 6 times more amperage in circulation
between L and C then is inputed by the source.
     Now to match for the existing design using 20 nf, when the arc gap
fires the 150 nf capacities appear in series for 75 nf, almost four times
the previous 20 nf value. As previously noted the similarity to the Marx gap
is that two capacities are charged in parallel and discharge in series at
the arc gap midpoint. It should merely then be necessary to tap the former
12 turn primary to also obtain almost 4 times less primary inductance.

Since stupendous L values exist for the purpose of both raising the input
voltage available at arc gap; and quenching the arc once the arc is
initiated, it does seem rather silly to suppose that by merely allowing a
couple of primary turns placed in series with an arc gap matched where the
TC secondary resonance is known; might produce results. If it does this then
would allow for speculative primary designs where primary
mutual inductance with the large exterior L values might be put into play.
 
 Do you have any photographs of your coil? 

I will soon work on showing flicker jpegs showing the both series and
parallel acting Q factors for the newer 94 lb system. It is balanced very
well but when employed for voltage rise a mis-balance is noted. This will
take several jpegs and days; busy with spring planting right now.
Sincerely HDN
