Hi list,

Took quite a while but the isolation transformer is taking shape.

Specs:

General:
#10.5 gauge magnet wire is used throughout (.094 dia. bare)
Transformer will be under oil.

Coils:

3 primaries:
240 vac input -at- 12 amps each

4 pairs isolated secondaries:
Each pair consists of
2 secondaries at 60 vac output -at- 12 amps each

Insulations:

Insulation between secondary pairs and the core:
2 sheets polypropylene 1/16" thick each.
(preformed then cut to size)

Insulation between primaries and secondaries:
2 sheets polypropylene 1/16" thick each.

5/8" separation between secondary pairs. (insulation is the oil used)

Testing has confirmed that each secondary has the same amount of turns as
well as the primaries. (voltages are equal)
