Posted by Bert Hickman on 10/25/2003, 2:10 pm, in reply to "Tesla Oscillator" Hi Pete, Thanks for the kind words! The machine you're describing is the Tesla Reciprocating Mechanical Oscillator (sometimes called his "Earthquake Machine") patent number 514,169 (Feb. 6, 1894, "Reciprocating Engine"). There's also a related patent, 511,916 (Jan. 2, 1894, "Electric Generator"). The device created low frequency vibrations which, if tuned to a structure's natural resonant frequency, could cause increasingly larger oscillations within the structure until (in theory at least) it shook itself apart. There is an in-print book available that decribes the device in great detail: "Nikola Tesla's Earthquake Machine: With Tesla's Original Patents Plus New Blueprints to Build Your Own Working Model" A web site that you may also find useful is at: Hope this helped, and best regards, -- Bert --

Posted by Bert Hickman on 11/1/2003, 12:32 pm, in reply to "Re: Tesla Oscillator" Hi Pet, Thanks for the kind words! Your professor is indeed correct. The worst type of short circuit is a phase-to-phase "bolted fault". This type of fault has been known to cause thick busbars to bend like pretzels, easily breaking off their ceramic standoff insulators, causing thick internal windings of power transformers to bend, crushing insulation between windings, and sometimes even causing them to explode. For low impedance devices (generators and large power transformers), external inductance or internal leakage inductance may be purposely added to limit the bolted fault current to levels that won't destroy the generation or transmission equipment, and to prevent the destruction of the Oil Circuit Breakers (OCB) whose job will be to valiantly interrupt the fault. Good luck in your studies and best wishes, -- Bert --
