Abstract
An arrangement for potential-free measurement of current flowing in two primary conductors arranged in parallel in opposite directions of each other. The magnetic differential field is detected by a differential field sensor. The primary conductors and the differential field sensor are disposed between two metal shield plates made of a highly permeable material. Each shield plate has a web and the webs extend on both sides of the arrangement of the primary conductors in parallel to the arrangement. At least one shield plate has a U-shape in cross-sectional planes having one pair of limbs that extend at a right angle in a longitudinal direction to the U-shaped cross-sectional planes. At least one limb of one shield plate is aligned toward the other shield plates on one of the limbs while leaving an air gap.
