I have a large transformer core that I want to wind for my inductive
ballast - 13mH. It must handle 3kVA without saturating, so could
some of the transformer experts tell me if my core is large enough,
and minimum number of turns required?
Overall dimensions are 7.5" x 6.25" x 2.5"
cross sectional area 1.25" x 2.5" on perimeter sides and 2.5" x
2.5" in center leg of the El shape.
This is from a 1kVA Topaz isolation transformer, but the size of the
core seems like it can take much more power.
