High Voltage Transformer Autopsy

at 6:17 pm. Filed under Electronic Hacks


Ever want to see what is inside a huge High Voltage Transformer? The Geek Group got one donated and took it apart for everyone to have a peek. The transformer is an old medical XRAY transformer, there is a huge safety disconnect contactor under the top cover and the entire case is filled with mineral oil for high voltage isolation.  They spread it out over 3 videos and some of it is a bit slow. The first video doesn’t show much other than using a fork lift to lift the top out, the second video around the 8:40 mark shows the transformer being lifted out of the can. Video 3 goes over much of the guts of the huge transformer. At 4:50 in video 3 you can see a huge stack of series capacitors that was housed in the metal box on the side. Interesting how the paper holds up after many years of being submerged in oil.

    The oil in the transformer most likely comes with a danger -> PCB !

    And the anonymous donator saved the cash for proper waste disposal.

    Andy, I believe he mentions the oil at some point and that it is safe. Not something you do in your own home without being a professional.
