Phenomenon observed by Tesla

[Raui]

I was just wondering if anyone has any information on the effect Tesla observed when the switch of a dc dynamo of high potential was closed. Lindemann said that the engineers of the time put it down to be some sort of 'bunching effect'. I don't want information on radiant energy rather I just want to be able to put a reliable reference in my paper I am writing about the phenomenon where when the switch is closed there is a moment where no current flows.
Thanks,
Raui

I'm afraid i can't help ya there, but when you finish your paper, would you put it up here. I would like to hear what you found.

peace

I dunno wether this helps you;

Start reading from Shocking Discovery.

I did some work several years ago looking at Tesla's experiences with these phenomena.
Here's one of the traces from the wire explosion work I did.
The trace is made by sandwiching the wire between 2 pieces of fine-art paper and compressing it with a weight. Then the capacitor bank is charged to a high voltage and allowed to over-volt an air gap, through an inductor, and through the wire to be exploded. I was using 0.3 microFarad charged to about 60 or 80 kilovolts. The wire was usually #40 or #42 enamel-coated copper magnet wire. If I got the parameters just right a trace like below was produced. Too much energy and you totally vaporize everything. Just right, and you can see where the globules of molten copper are ejected (always on the outside of the wire's curvature) and re-solidify some distance away. Sometimes, amazingly, the tiny hair-like tube of the enamel insulation would remain behind, seemingly intact or in only a few pieces, while the copper vanished.

I think the phenomenon of delayed current to the load happens as a result of an interaction between inductances in the lines and load, and the phase of the applied current at the moment of switch closure. The first thing that happens is that the inductance sets up the magnetic field, and only after this does current reach the load.

Very cool experiment you did there TK. Can you draw up the schematic of the circuit you had?
