Here is what I'm trying to do. I have a transformer, 1600VA unballasted. And I wan't to short circuit the secondary. If I just do that without anything in series, it draws some 80A from the wall, which is not good. Then I remember about using inductors in series. I got some formula to calculate de impedance based on the 60Hz from mains and the inductance measured on the windings. I made it with a old iron core.
The question will be obvious to most of you, but not to me. I saw some people around the internet, a lot actually, say that you can limit AC current without dropping the voltage. I just can't understand that. Then I tried it to see if it works that way, but when I connect the inductor in series with the load, only ~60V reach the load, from a 127V wall socket. I'm using a 4.65mH inductor which at 60Hz, would be 1.753ohms.
The main question is if can I limit current without dropping the voltage that much? I need at least 120V, 60 is too low.
