Inductive sensor for measuring the current in a conductor

摘要

The windings (10,12) are wound on amagnetic bars formed into rings which have discontinuities (20). The windings surround a conductor whose current is to be measured and the discontinuities are evenly balanced. Each winding has an even number of layers and corresponding layers are wound in an opposing sense. The windings are encased in a protective box (14) which is filled with resin
