Wind Tesla

The winds Tesla or transformer of Tesla is an electric machine functioning under Alternative course and making it possible to reach very high voltages.

Components of the assembly

a food High voltage made up of a Transformer being able to provide several kilovolts and possibly safety device.
a spark-gap with stopped sparks or rotary.
a Condensing able to resist a tension higher than that of the food.
a cash winds primary broad, few whorls, and able to resist high running.
a high secondary reel, counting many whorls.
a metal part being used as electrode of discharge, whose capacity must be known and adapted to the circuit. Its form imports little: there exist models in the shape of sphere, cone, point, of torus,…

Assembly of the components

The various elements are assembled in this manner:

the two diagrams are electrically identical
the secondary reel has a diameter lower than that of the primary reel: they are threaded one in the other, their axes are aligned.
the secondary reel is connected to the ground at its base and the electrode of discharge is fixed at its top.

Operation

Once energized, the feeding system charges the condenser. When the Potential difference at the boundaries of this one is sufficient, an electric arc crosses the spark-gap and the condenser discharges in the mesh containing the primary reel. It is an intense and high frequency discharge: one thus obtains in the primary education reel a high frequency and high alternative course intensité.
Like any solenoid traversed by a current, according to the laws of the magnetic Induction, the primary reel produces a electromagnetic Champ in the medium which surrounds it. This field is him also intense and varies high frequency.
The important variation of flow through the secondary reel will induce at the boundaries of this one a potential difference proportional to the report/ratio of the numbers of whorls of the reels secondary and primary education (see the operation of the transformer single-phase current).
The most important stage of the adjustment of the apparatus consists in obtaining the Résonance between the frequency of the primary education circuit and that of the secondary circuit. This adjustment is delicate because the electromagnetic fields generated by the two reels are perceptible remote (for example to wind the electric cables can have an influence on the behavior of the circuit).
Once resonance reached, the tension induced at the boundaries of the secondary reel is maximum (several thousands of volts even several million for the great models). As these tensions are higher than the dielectric Rigidité of the air, from the electric arcs will spout out of the final electrode in all the directions.

Apart from its theoretical and teaching interest (because it allows impressive demonstrations) this invention does not know any application currently practices.
