This may be an Isolation Transformer, But he says this can b use in 11Kv > 230v Distribution tx .How ??????

@sunishmenon the appliances wont be giving the best output since the impedence matching to a load designed for 30hz ac will be lost, and the power consumption will be as low. still there might be an optimum limit, sorry i cant make a good guess of the numbers, for aerospace applications we have motors that are custom built for higher frequancy ~500 hz sources.

@arlov333, Thanks. Then it may be the same thing. But will devices like refrigerators designed to work at 50Hz work on 20Hz, as sha6441 said?

@S200773, What do you mean by same amount? You are comparing with 12VDC or 24VDC. 240VDC gives you more shock than 240VAC. And the video posted by ariov333 shows that skin effect is true for human beings.

[S200773]

@sha6441 if its true then why same amount of AC gives shock but not DC. The skin effect is true for non living things like metal conductor (wire etc).

[S200773]

don't believe him you will be dead,Prabhakran is having some setup need to be check is it real what he is showing as per my opinion its not possible for any device to sens the medium of current flow, only amount of current flow. it is a very big subject to define behavior of AC (Thanks to Nikola Tesla). in short Its Fake.

.. most probbly this is skin effect.. ie when the frequency of an electromagnetic wave is very high it conducts only thru the surface of a conductor , not thru the inner body of the conductor... his device might be increasing the 50 Hz mains frequecy to many folds, so the current will pass thru the outermost layer of human skin and since this layer is dead skin, we dont feel any shock. this is just basic electromangnetic thoery.but this may not the good for normal equipments designed to 50hz

@arlov333,

What frequency changer?

[sunishmenon]

240V DC?? Never. He is clearly saying that this can be installed on transformers. DC cannot travel much distance like AC. And if you feel 240V DC does not give shock, try to put your finger inside the DP of train compartment, which contains 110V DC. Moreover, how can we use our existing refrigerators, motors pumps, grinder, mixie, etc. on DC? This is something else. Enthaayaalum kollaam. But oru doubt. What if a person holds both phase and neutral? Fuse pokunnathinu munne aalude fuse pokumo? :(
