ABSTRACT:
A controllable inductor comprises at least a tubular core (13) a main winding (5) surrounding the core, a control winding (13) passing substantially axially through the core, a ground part (15) arranged inside the main winding and an element surrounding the core and adapted to carry the main winding wound outside thereof at a distance to the ground part while creating a voltage taking air gap between the main winding and this part. The main winding has a first end (10) thereof on high potential and the potential falls towards the second opposite end (11). The element carries the main winding at the first end (10) at a larger radial distance to the ground part than at the second end.
