Three phase transformer arrived for saturation experimentation.

Hello Aaron, HV grp, and all:

Dimensions of core:
4? wide, 8? high, 9? long, inner I cores 2?

Output: Straight forward Wye configuration touted 
to deliver 5KV@1 Amp. All three winding wires to 
wye neutral easily accessible. Each winding has a 
DC resistance of about 40 ohms. Inductance is 
about 13H on a cheapie meter. Guessing 18 AWG stranded

Input:

There are three inner taps labeled 240v feels 
like a 10 or 12 AWG gauge wire. On the outter 
edge taps are (4) taps/winding these decrease 
closely lower R ohm increments beginning at .9 , 
.8, .7,.4 ohms. This getting my Beckman. 
Inductance respectfully: .193, .179, .166, .004 
hmm? lablels respectively: +10v, 0, -10, 208v .

Let me make some assumptions the inner Hv winding 
should be disconnected from neutral and connected 
to the DC supply. This consists of a 35 amp 400 
PVI Bdiode on a pIII heat sink. For starters I?ll 
use my 1256d since it is set up anyway. I am 
considering using filtration of 400uf separated 
by a 23 mh heavy choke 200UF out. Maybe that is 
unneeded but there won?t be any harmonics or 
ripple as the current ramps up. I propose to use 
the 240v outer windings to go to my pig, no 
neutral. BTW the 208 winding seems heavier?hard to tell.

Ok: those that have suffered through this so far 
and know the math, how much voltage/current do 
you estimate it will take to Sat this iron? What 
do I do with the input windings to the center 
control core, and the output winding of the outer 
controlled coils. Shorting em will heat things up 
fast. Load them maybe? Suggestions are requested. 
This may be easier with a three phase really 
heavy duty filter choke. I see them on ebay in fact have a few smaller ones.

My pig is grounded as will this transformer. I 
have three 4500 watt hot water heaters for 
starters. I won?t go past 9KW, it would be pity 
to smoke this perfect 883a transformer!

Thanks Much,
Jim Mora
