Is that Metglass tape?

Mr T
Holy Crap!!,I had no Idea!!

Sweet!!

You freakin Whacko!!
You look good on that beast!!

Whats that red one ?Runs on wood gas?

Or you gonna sell  barbeque weenies on the thruway to help pay pauly ?

I NOTICED IN THE BELOW VIDEO TEST THAT THERE IS INDEED FLUX IN THE OUTER RING ON NO LOAD AS THE FEMM SUGGESTS ALTHOUGH I WOULD HAVE NOT PREDICTED IT.

CHEERS

Thane, to avoid misinterpretation, here's the Femm result in case no secundary load is present.
You'll notice that indeed there is no flux in core3, as one would expect.
I don't understand why there is some in your setup in case there is no load......

(The earlier results I showed had some secondary load current included. That is why they have flux in core 3)

The measurement method you use is a bit doubtful though, using a current clamp to measure magnetic flux.
Those clamps are normally made out of ferrite (so high permeability).
Putting such clamps on a transformer core should not give any flux in the clamp core, even if there is flux on the transformer core.
But you showed it obviously does. So, big question marks here.

I would just use a few (10-20) detection windings on those cores to measure the voltage over those windings with an oscilloscope. That probably will give you a more reliable and accurate representation of the local flux.

Thane, gaps like the image below has?

I had some thoughts on the consequences of having all transformers used in average life changed into BITT onces.
In that case the energy plants need to provide mainly blind power (PF=0).
I wonder whether that will actually be the case in the end and whether it will be technically feasible at all to deliver mainly blind power to all consumers.

So, the BITT looks like a very charming solution for individual cases, but for such main stream changes it will be a different story.
Power plants probably will change the way of billing the delivered electricity if delivery of mainly blind power is technical feasible at all.

B.t.w. In my country (Holland) private consumers do not pay for consumed blind power.
But companies do pay for this already.
