no ... I had short-circuited the output ... but, if instead the short, had been on the opposite side of the coil, that is, what changed at the input!? 🤔
ah, I thought you were referring to the variac, so the transformer I tested with the 1/2 strength variac during the short had V1 / V2 = 0 V1 / V2 ... but instead at the input of the variac what voltage, was present in that instant !?
Already, he hasn't smoked, only the cable at its exit at the point where the phase touched the neutral, but I immediately disconnected, as if I were the switch; who knows if there is a mathematical formula to be applied to the electronics in these cases, even out of simple curiosity? .. A few...
okay, i used the meter, and rotating slowly i did not notice anything abnormal except a couple of volts, less, however a voltage that was not stable on the DMM (+ - 0.5V AC) but i believe this is regular👍

hi, mr ... I would say a small 3.5A x230 V ~ pik-up ... the short was interrupted by me, because I was holding the contact...for scheme,above the link 🙂
Hello,while I was checking another transformer through an autotransformer and some wires in the air I produced a dead short on the output of the autotransformer ... but the thermal switch upstream of the two transformers has not tripped. What tools could I use to check if the first Has the...
