Question:

Can you connect two transformers?

I have a transformer of 12060 Volts and a transformer of 15000 Volts, both neon-sign types; if I wired them together, would it amplify the output voltage or have a catastrophic effect that would end the world as we know it?But really, can I wire them together for an added effect of some kind?Thanks.

Answer:

I would not recommend it.
If you connect the output side of one to the input side of the other, the second transformer would output a very high volatage, but a very low amperage. Until the internal insulation failed and possibly started a fire. The very high voltage, low amperage output would not be useful.
Yes the PS and PS 2 are likely problems. The switching type are likely rare for this high a voltage. Use the transformer with the broadest surface as the base and mount the other at least two inches 5 centimeters above it with very high voltage electrical insulators. This MAY reduce the problems with leakage to the case and excessive stress on the internal insulation. Connect the primaries in parallel; the secondaries in series and you MAY get 27000 volts, perhaps MORE. Be prepared to cut the power quickly if either transformer makes arcing sounds or smokes. Be careful, these transformers often give DEADLY shocks. My advice is sell them cheap on E BAY before they put you in an early grave. Neil
If you connect the output of one to the input of the other, you will have a catastrophic effect immediately. You could connect the inputs in parallel and two outputs in series but you need to know how to get the phasing right. You will get 27000 volts. PS The series connection will work poorly or not at all if the transformer conains a switch mode power supply. PS2 You also need to deal with the effects of an internal connection between the output and the transformer case.
