Abstract
A power or regulating transformer with voltage regulator includes regulating windings made of a flexible conductor having an electric field containing mechanism that forces the electric field due to the current in the winding to be contained within the flexible conductor. Since virtually no electric field is to be found outside the flexible conductor of the regulating winding, the regulating winding may be formed without having to consider the electric field distribution, thus providing for a transformer with a favorable regulating winding design.
