Hello Brad.
i can`t say more to you, but it`s not a problem - Richard can, so
sit down, turn off lights and enjoy the story :-D

Subj: 10KVA Tesla Coil

BC> I remember you mentioning/offering a video tape of some
BC> Tesla coils you had made. Could you please repost the
BC> cost/contents... Thanks
OK, lets see...
The video tape is a brief look at some standard 1/4 wave Tesla
work, though some people have requested, and have received,
videos that include my introductory work of the three coil Tesla
Magnifier system. The basic tape that is most requested is two
hours in length, SP recorded on VHS format. It is a high quality,
one-off, master.
The tape opens with my 10KVA (10,000 watt) "pole pig" or power
distribution transformer wired in reverse. This xfrmr has two
high voltage bushings and is made to step down 22,890 volts for
120-240 use. I use a power control cabinet (ganged variacs with
filters and switching equipment) wired in series with an arc
welder (to limit the current). The power cabinet and wiring are
detailed. Using the cabinet/current limiter I am able feed a
current limited controlled voltage (0-280 volts, 9-60 amps) into
the low voltage windings of the pole pig.
I bolt two 3/8" soft copper pipe "rails" to the high voltage
bushings on the xfrmr, and fire a Jacobs Ladder at up to 8000
watts at 20,000 volts. As the xfrmr growls, some of the resultant
arcs threaten to catch the garage ceiling joists on fire.
I then construct a high voltage RF filter board and test it
across the high voltage side of the xfrmr system. Then I set up
my large coil for some low power tuning and testing. This coil is
10-3/4" in diameter, with a winding of single layer #21 magnet
wire. The coil has over 900 turns, and the length of the winding
is 32 inches. The coil is topped off with a 20" diameter toroid
discharge terminal. The primary coil (100' of 1/2 od soft copper
water pipe) is set up with two .1 uf commercial pulse discharging
capacitors (rated at 45,000 volts AC) in series, and we excite
the circuit with a simple static spark gap and a couple of 9000
volt 30 ma neon sign xfrmrs. The entire ceiling network of
florescent lamps (and even disconnected stored bulbs) glow from
the radiant energy. No spark yet... But I grab a hard copper
water pipe in my bare hands, and standing on a plank, draw a foot
of hot spark from the discharge terminal.
Next we clear out some garage space and hook the coil up to the
pig for some "run in". We are using a fixed speed rotary spark
gap and the coil really wails with 60-70 inch sparks indoors,
again threatening to ignite the ceiling joists.
We cut to some small coils here as I develop a static gap system
that uses a shop vacuum motor to quench (stretch and cool) the
hot primary arc. I fire using homemade capacitors and a pair of
15,000 volt 30 ma neons. Once I am satisfied with the new gaps,
we place them in series with the rotary gap on the big coil, and
get better performance. The new gap system removes the overload
from the rotary. Again the ceiling threatens the catch fire as
sparks from the coil completely penetrate the wooden joists as if
they were paper.
Next I move the coil outside and increase the input power by
opening up the current limiter and letting it rip. The new gap
system holds up, and thick white arcs 8-9 feet long strike
everything within reach. The spark gaps light up the entire back
drive. The coil really howls! Lots of current in the continuous
output... These are not Van de Graff discharges!!!
The spark is still not long enough for me! I build a new
discharge terminal out of flexible plastic drain pipe and
aluminum foil tape. We set the coil up again in the back drive,
retune the system for the new discharger, and open it up again.
The discharger is mounted a little too close to the coil in this
test series, and the spark is caught up in the primary/secondary
field flux. Arcs to the grounded rail protecting the primary and
tank circuit are white hot, thick as a man's leg, and 4-5 feet
long. The power does drive a few long strikes away from the
system. The photographer moves up, then moves way back as the
discharge nearly strikes the camcorder. I really let the coil
burn; 8-10 KVA input in several runs of 3-5 minutes. We record
and measure point to point strikes from 7.5 to 11 feet. Other
sparks completely leave the field of view of the camcorder, and
exit the screen 15 feet from the coil discharger.
I end the tape with freeze frame and slow motion shots. Giant
sparks are caught by the camera walking the ground all around the
system (100 to 132 inch strikes), the basketball net is hit with
a full current strike (90"), the garage is struck and a corona
cloud lights up the brickwork (117" strike), etc...
Terms for a copy of the video are as follows: Send me a blank
high quality VHS video cassette. Include a first class postage
pre-paid self addressed mailer, and $10.00. I will copy the video
onto your tape, pop it into your mailer, and send it back.
I must include the disclaimer: This work is dangerous. All of the
equipment and experiments featured have lethal potentials. I
cannot be responsible for the safety of anyone who reproduces, or
attempts to reproduce any of the equipment or experiments I
feature on the video.
