Abstract

The transformer has a ferromagnetic E-core (E) with forms a double-closed magnetic circuit together with a rod-shaped ferromagnetic yoke (I). A first coil (1) is wound on the middle limb (EM) of the core, a second coil (2) on the middle limb, a third coil (3) on the first outer limb (ES1), and a fourth coil (4) on the first outer limb (ES1) Independent claims are also included for: (1) an E-E transformer; (2) using the transformer in a physical-electrical measuring sensor device.
