Tesla knew that if he was to make this work he needed to provide a voltage potential to attract the real charges (current or flow of those charges) so he devised such an experiment. HV souce pulsed one way to provide a pulsing potential and then let it relax and draw the current into his load. He used air cored transformers of special design to provide the higher voltages needed to attract massive currents as the source then had two antennas one in and one out. One was made with more surface area then the other but the mass or weight of them were matched. This provided the imbalance that he needed or the flow. Then in order to use that flow or charge in the system on one side only did he inserted the load between the hv source and on of these antennas. Of course the load had to be capable of both high voltage and high current just not at the same time since voltage leads current or comes before.
Let me provide you with a picture of such a device:
.................................N
......o-------o-------O.Arc.O----o (special transformer) o----o(load)o-(ant)
HV ..........(Cap)...........S..........P.(.......... ...............).S
......o-------o-------------------o (same transformer.) o-------------(ant)
The left hand side of this circuit is HV through a transformer as well but I believe that was just a normal transformer to provide the necessary HV for the arc space. The arc space was magnetically quenched to provide faster arcing.
The special transformer was immersed in oil for the extreme experiments he used and is not necessary for lower voltages but I have no clue to the relationship of what voltages needed to be present. He used the oil as a better insulator then they provided at that time. the coils were wound on a wooden dowel and the primary was wound first then the secondary was wound after on top of the primary. Check figure 3 in this link "Experiments with Alternate Currents of High Potential and High Frequency" by Nikola Tesla ...
There is specific details about the transformer that need to be adhered to in order for this system to be externally quiet electronically. Shielding being one of those requirements. Also I think this is where he got the idea for Coax cabling to direct the radiating event to the external parts of the whole device but his version seems to have the shielding not connected at all to anything but is purely to conduct the radiating event from the wires along a certain path. Where that path ended up is somewhat buried in his descriptions. Maybe someone will catch where that was I have missed that part obviously.
