Transformer

No, of course there were no transformers when Tesla was alive. It was years after Tesla's death that his cryptic notes on the induction motor and the Tesla coil was ever successfully assembled. What's even more amazing is how Tesla designed the synchronous generators later used at the Niagara power plant along with the entire AC voltage distribution network for Westinghouse from Oliver Heaviside's theoretical work long before transformers were a dream in a physicist's mind.

The story on Tesla and transformers is truly amazing!

Hah, that's a cute link engine, where's the setup for that?

We should suggest the O.P. read one or more of the Tesla autobiographies, concentrating on the period immediately after his arrival in the U.S. His relationship with Westinghouse as opposed to Edison was all about AC power rather than DC power, attractive first because transformers could be used to step voltages up and down, and secondly because of Tesla's love for rotating polyphase machines. But following Tesla's early career, it's clear that his strongest interests lay elsewhere, such as pulsed high-voltage, Tesla coils, etc. The heavy lifting for all the complex transformer designs and rotating machine designs of the age must have come from many other electrical engineers of that age, who toiled away working out the details of how to build all the large-scale machinery involved in the widespread deployment of Westinghouse's AC power system before the turn of the century. Their story is largely untold or at least an unheralded.

You can type in what you want, copy the url and post ... hilarious isn't it.

A nice series of YouTube videos on the life of Tesla would be informative too, here is one of the series, please download all of them...

It was Farday who interested in chemistry who didnt do good education discovered electromagnetic induction/em induction all did R n D after that. -Hit

what is the difference between tesla coil and conventional transformer?

is the conventional transformer is a developed version of tesla coil?

Very good answer Dabrain. The only correction I wish to add is that there is one very significant use that Tesla found for the Tesla coil, the automotive ignition coil. The points opening up would now cause the resonance now generated between the primary coil and capacitor now coupled to the secondary side as a brief high voltage oscillation that would jump the gaps of the moving switch of the distributor cap and rotor along with the spark gap found in the spark plug that ignited the fuel.

Oh, one other correction. A Tesla coil is not an isolating transformer but it is just as much of a transformer as an autotransformer.

GA DABRAIN.

I relied on Wikipedia to research this answer.

It's widely thought the AC power-system ideas stemmed from Tesla, but this is inaccurate. With respect to the very-important AC power transformer, Lucien Gaulard of France and John Dixon Gibbs of England were the original developers of the modern transformer, in the early 1980s, and in fact their patent applications were denied based on earlier work by Sebastian Ziani de Ferranti in England, and others.

Starting in 1882, de Ferranti worked in this area, and completed a modern power station in 1891 for the London Electric Supply, at Deptford, supplying high-voltage AC power that was then "stepped down" with a transformer for consumer use on each street. These were modern AC power transformers in that they had iron cores, etc. He obtained US patent 341097, applied for in 1884.

William Stanley, Jr. was a physicist born in Brooklyn, NY. In his career, he obtained 129 patents covering a variety of electric devices.

In 1885, Stanley built the first practical alternating current system based on Gaulard and Gibbs' ideas and he developed generators, transformers and high-voltage transmission lines, first deploying them in 1986 along the main street of Great Barrington, MA, where he lived. Westinghouse hired Stanley as his chief engineer at his Pittsburgh factory. So that entire history goes back well before Tesla's time at Westinghouse. [In 1890 Stanley founded the Stanley Electric in Pittsfield, MA and in 1903 the GE purchased a controlling interest in his company.]

Tesla should instead be credited with creating efficient polyphase generators and motors, in the mid 1880s, very important in large systems. He can be credited with being a good early driving force behind Westinghouse's young company in the late 1980s.

The first commercial power plant in the United States using three-phase alternating current was at the Mill Creek No. 1 Hydroelectric Plant near Redlands, CA, in 1893, designed by Almirian Decker.

I have read that Westinghouse paid $1M to Tesla for his help and for the rights to his inventions, and Tesla used that along with money from wealthy investors and patrons to pursue his true interests. The air-core resonant high-voltage Tesla coil transformer came later from this work.

True, The motors supplying the current drove batteries (all DC) and then through crude inversion produced AC. Some skipped the batteries but still a DC source. Poor quality Ac power at best. (I need verify this more)Tesla picked up the ball and ran with it. The AC polyphase motor/generator are the big leaps to make an industrial grid. All of the inventors you mention developed their devices after Tesla's first patents. Tesla's version of AC generation, wireless transmission, and resonance are his true genius. His work like all inventors is on the foundations of other ideas.

Quote from DABRAIN: "Vibrate something properly and you will get it release its energy."

Further explanation with examples please.

Quote: from DABRAIN: "Tesla failed to able to control the released energy. The atmosphere to ground circuit (lightning) could be tapped through resonant pulsing. Tesla achieved this feat but was unable to control it with any practical means. The output was very low but supply was relatively infinite to need."

Again, detailed explanation.

Quote from DABRAIN: "Unproven, is that a harmonic node could be hit in this circuit and tremendous amounts of current could be accessed. Theory good but very little proof other than conjecture and speculation."

Theory as in mathematical? Or in what terms? Explain.

.. and finally: "Om" is the universal vibration in many chants and meditations."

I don't disagree that vibration (as sound and light) is the watchWORD of the Universe. But unless you can point to practical demonstrations or experiments for others to try, it serves little point to imply you know and/or understand these things. Just be clear about what you know and what you don't. And if you do know something but don't want to share it, then specifically state that. Of course, at that point, fewer people will give credence to what you are posting regarding this subject.

I really think there is MUCH to be learned (or relearned in many cases). I think there are things to be learned that would qualify for science fiction by today's science. But the language you are using is too vague and needs to be clarified. Please do so.

OMG 1. Early respondant mentioned resonant spark gap, Also, crystal oscillators, piezoelectrics, and other many small devices. I am not touting free energy. There does need some fuel to make the vibration release or control energy. Large scale applications included the two large Tesla coils that were made in Wardenclyffe, NY and Colorado Springs, CO by Tesla. Another exists in the desert somewhere in California. From Barton Anderson: "1 Inductive reactance (Xl) increases as the frequency is increased. Capacitive reactance (Xc) decreases as the frequency is increased. Because of this, at some frequency, these reactance's must equal. The frequency when Xl = Xc is denoted as the Resonant Frequency (fr). The formula to determine a resonant frequency in an LC (tank) circuit with an AC waveform is: fr = 1 / (2 * pi * sqrt(LC)) The importance of resonance is the maximum current characteristic that accompanies resonance in any LC circuit. Frequencies above or below resonance drop off available current drastically. Maximum current is produced because Xl and Xc are equal and opposing reactance's, causing a cancellation to one-another. This reduces reactive resistance to the AC waveform and therefore produces a maximum current characteristic. (B.H.)The amount of energy available to oscillate the LC circuit is a function of the tank capacitance and the voltage at the time of the sparkgap conduction. This is typically known as the bang size. Bang size represents the maximum amount of primary tank capacitor energy that is available for transfer to the secondary coil each time the sparkgap conducts. Mathematically, the bang size rated in joules will be: Ep = 0.5 * C * (Vp^2) THE SECONDARY LC CIRCUIT The secondary is an air-core coil with many more turns as compared to the primary coil. The oscillating energy from the primary coil and capacitor induces the secondary coil by way" Large scale Tesla coils used this principle. The primary circuit is the atmosphere and the secondary circuit is mated to the ground through an earth electrode. Tesla and other achieved this circuit. It brought in energy relative to Hertzian antenna priniciples. The Tesla Antenna was an alternative name. Tesla made the claim that he discovered the resonance of the earth but its accredited to Schumann and it is called the Schumann resonance. Many have tapped the earth resonance. Schumann had to resonant the atmosphere to prove his point by Tesla's method. From "The Classic Tesla Coil A Dual-Tuned Resonant Transformer"by Barton B. Anderson ... "3 to X% * Ep. Using this variable, the output voltage can be found: Ep = Initial Primary Bang Energy Ep = 0.5 * Cp * (Vp^2) Es = Energy Transferred to the Secondary Es = 0.5 * (Cs + Ctop) * (Vout^2) Assuming Es = X% * Ep Vout = Vp * sqrt (X% * Cp / (Cs + Ctop)) (B.H.)In a typical 2-coil system (Classic Tesla Coil), Vout will be in the range of 10 to 30 times the primary sparkgap voltage (Vp). Notice the turns ratio between the primary and secondary windings has no direct bearing on Vout. However, it can be found that there is a relationship between the relative primary and secondary coil inductance's: Vout = Vp * sqrt (X% * Ls / Lp) IN PRACTICE (B.H.)In practice, the actual interrelationships that govern coil operation are considerably more complex than implied here. Simply aiming for higher V out will not necessarily deliver better performance. The actual efficiency of "incinerating air" (getting the longest arc for the minimal amount of input power and coil size) is a very complex and poorly understood combination of bang size, primary and secondary impedance's, coupling coefficient, sparkgap quenching, streamer loading, top-load capacitance, operating frequency, break-rate, charging circuit, and many other variables. (B.H.)" As for hitting the node, HAARP and other similar arrays are suspicious attempts at attempting this feat. Highly Speculative though. Like a bridge, if enough resonant frequency is sent through it will began to vibrate violently and the crash to the ground. There is a "a harmonic node" when reached will collapse the bridge. The air to ground circuit may also contain this node and be able to release incredible energy.
