<p>A transformer with at least two windings, and associated yokes, has the windings mutually rotatable around one axis and has air gaps between the yokes for temp. compensation. These yokes are fitted with rings close to one another and made from ferrites and/or coiled ferromagnetic bands. The yokes may have a U-shaped cross-section and a circular air gap is between the limbs of the radially innermost yoke and the limbs of the outer-lying yoke. The contact surfaces of the rings of one of the yokes lie in radial planes.</p> |
