    Size matters

    I've got these transformers already from before:
    ---------------------
    TOROIDAL TRANSFORMER TD300-1120-P; DN19551;

    300VA; 60 HZ; Primary - 120V; 160 degrees of winding on

    toroid surface coverage.

    Secondary to be wound by customer. 50P
    -----------------------

    Can I use one of these instead of buying another one? If so, what do I need to know/do?

    Thanks,
    Digits10,
    Measure the OD (outside diameter), ID, and height. If it's same as ours, Clarence and I, then can give you some pointers to winding yours.

    Clarence was patient to show me how to wind mine. We wrapped and tested two before getting it right. But once you start wrapping it kind of falls in to place and you'll get the hang of it.

    I think I bought 400 feet of #20 magnet wire to start with.

    But tell us the dimensions first.

    Edit: Sorry didn't see Clarence post until after I posted. It took two days to wrap and painful. But possible.

    As I said before - that one will not work!

    The CORE is good but that's all !

    You would have to strip it completely and re wind it yourself with 660 turns
    covering the whole thing.
    Believe me , you do not want that!!!!!!!!!!
    I will never do it again - it,s that BAD!

    Best,

    Clarence

    Wantomake,

    Tomorrow AM I will be helping my daughter-in-law in stall a new water well tank.
    However I will be checking in quite often to see if you need anything.

    Best to you J ,

    Wantomake ,

    If you have anything lower than 90 you cal use that . say a 75 v?
    EDIT: Did you see the info on the order method for the same toroid coil we made?

    I don't do diagrams or schematics.
    Look at the last photo I sent to Wantomake - it says it all.
    The toroid , as I said, has a special CORE with a special 660 turn winding.

    The unit is constructed so that the extra comes from the GROUND!

    The attachment shows where you can order the same build that We made by hand. The lead time for one of these orders is two weeks.

    Best,

    Great. Mains & a ground rod is no problem here. Any chance of sending a diagram when it's convenient? I started (and stopped) with the two toroid transformer design back at the beginning of the year. Looks like I need a single coil & a gdt?
    On an aside - so the electricity being pulled (the extra amps) - where is it coming from? Radiant energy or something?

    digits10,

    If you are using mains - probably one.

    If you don't have the special toroid 660 turn # 20 AWG thatWantomake and I built the don't waste you time or effort. You will get nowhere in a hurry.
    Sorry bout that.

    Best,

    Mine already in use today

    Ok, you're using mains power. The shop is solar only. I can run a long drop cord to get mains. But I did get part way on the reassembly before leaving this morning. My inverter doesn't have GFCI as it's not growled at me any. But I did purchase a smaller inverter 750 watts pure sine wave I believe.

    I'll take this tablet to refer to your picture I downloaded.

    Will post results.
    wantomake
    Wanto make ,

    Sounds good to me.
    Used mine on microwave a couple of times today.
    My drop cord to it is a # 10/3 50 foot and gets the job done. If yours is longer it might drop some voltage and change power range of a micro-
    but I'm sure you already know that. Just thinking to my self.

    Hope you results are as good or better than mine. I say that only because of soil resistivity with respect every different location. This reclaimed swamp/rice land I don't believe is to hot.

    Best to you,

    Clarence

    GDT size?

    Clarence,
    These are the numbers on the GDT package.
    Y08SV-272B
    Sankosha
    Qty 10

    I think these are wrong voltage, size or something. I got a drop cord down to the shop. Plugged it into a GFCI receptacle and it (growled) tripped the reset button. Ok. Makes sense. So plugged in to a non GFCI receptacle and no problems. The power stops at the GDT. I carefully touch a 120 ac neon lamp across the GDT block connections and the load gets voltage. A lot of voltage. The neon almost melts!!!!! That's a direct short from hot to ground I know, but it's not that much voltage usually.

    But what do you think. Are these the wrong size GDT?

    I have more questions but those can wait.
    wantomake
    Edit: Datasheet says 250 volt ac rating. So I need correct size.
