Abstract

Apparatus and method for generating electric energy in an electric power transmission system includes an AC cable including a core, wherein a portion of the core is partially surrounded by an apparatus including a ferromagnetic body and an electrically conducting winding. The ferromagnetic body extends along a longitudinal axis and has, in a cross section taken along said longitudinal axis, a shape defined by an arc. The electrically conducting winding is wound around the ferromagnetic body to form turns in planes substantially perpendicular to the arc.

Claims

1. An apparatus for generating electric energy in an electric power transmission system, comprising:

a single arc shaped ferromagnetic body extending along a longitudinal axis and for an angle lower than 300° and

at least equal to 180°

; and

at least one electrically conducting winding wound around the ferromagnetic body to form turns in planes substantially perpendicular to the arc.

2. The apparatus according to claim 1, wherein the ferromagnetic body has a length from 6 cm to 40 cm.

3. The apparatus according to claim 1, wherein the single arc shaped ferromagnetic body is made of a monolithic metal or of a metal in the form of a plurality of lamellae.
