Technical Data of my Tesla-Coil


   
The HV-Transformer is a Neon-Sign-Transformer with 5kV - 0 - 5kV 50/70 mA = 10 kV and 500 - 700 VA.

The input power is 3 Ampere, that would be computationally 690 Watts.


The Primary Coil
(Primärspule)
from a copper tube 6 mm in diameter was wound. Inside diameter is 165 mm, distance between the windings 6 mm, outside diameter 403 mm with 9,8 turns. for mounting on the plate I used plastic angle 20x10 mm, which onto 20 mm distance pipes from plastic, with M3-srews was likewise installed.


The Primary Capacitator
(Primär Kondensator)
During a nominal output voltage of the Transformer of 10.000 volts. I mounted 20 impulse-condensers FKP1-100nF 650 ~ V of WIMA, on a hole raster plate to switch into series. The in such a way received capacity amounts to 5 nF.
Now the desired capacity from 20 nF to receive, I manufactured and parallel switched 4 of such plates. And it was soldered on parallel to each condenser a resistor 1M/1W, in order to avoid mentioned like already, remainder charges when switching off.


The Secondary Coil
(Sekundärspule)
On a PVC drain pipe 110 mm of outside diameters was wound 925 turns of 0.53 mm magnet wire, on a length by 536 mm. Remained above 20 mm for the discharge, down 50 mm for ground connection.


The Spark Gap
(Funkenstrecke)
7 or 6 subject is adjustable and consists of 8 copper tubes 12x1x50 mm.
Distance in each case 0.6 mm, the core of aluminum full material, for the better cooling and assembly in a Plexi housing, which with 230 V exhaust is operated.


The Safety Spark Gap
(Sicherheits-Funkenstrecke)
Is a double spark gap with 3 pieces 2.4 mm of tungsten needles, in brass pins is adjustable fixed.The middle connection is grounded. The spark gap is adjusted with 5 - 6 mm each distance.


Tesla Coil Safety Chokes
(Rückschlag-Drossel)
On PVC pipes 18 mm in diameter and 80 mm long are 50 turns magnet wire 1 mm wound. For the increase of inductance is installed inside a ferrite rod.


Topload Terminal I made several Toroids from aluminum flex duct. (see "pictures of the structure")


Power input filter
(Netzfilter)
it is importantly thereby no parts of the high frequency into the electricity power net flows back. I use a finished filter with 230 V and 10 ampere load, from a german electronic shop.
