Step down Transformer is it possible?

  1. Sep 16, 2012 #1
    Step down Transformer is it possible??

    20,000 Volts
    4 Amps

    its something very simple. There is a "free energy" device that generates the above voltages and currents. What I want is to drive it into a step down transformer reducing it ro 240 V and 10 A (EU household power ratings). Would you think that is possible? Is there a transformer like that in the market?

    Welcome to PF;
    I don't think dirty words are allowed here ;)
    Why would you want to do that? Its a scam!

    Anyway, you'd probably have to build something.

    AC or DC? In some countries the local grid is 20kV but usually three phase AC.

    Anyway why not just ask the inventor what he used :-)

    PS...

    No there isn't.

    Someone who falls for a "free energy" device at 20,000 volts is in line for a Darwin Award.

    Sorry gatzos, but no one is going to take "free energy" devices seriously here.

    Yes you can step down from 20000 volts to 240 volts, but how depends on whether the 20000 is AC or DC.

    I was curious about which scam it may be and gooogled the parameters we know... turns out that 20000V is a fairly common claim in the FE world, but the standout types are concentric electrode capacitors.

    ... but the Earliest I've seen date to Tesla.

    (apologies about the quality of the sites - it is representative of junk science I'm afraid)

    So I figure: something of this ilk.

    "turns out that 20000V is a fairly common claim in the FE world,"

    Perhaps they want to kill their customers before they turn up complaining that the devices don't work.
