Abstract
A land electrode has at least one feeding element connected to an electrode line of a high voltage direct current (HVDC) transmission system. The land electrode is in electric contact with a conducting medium and further comprises at least two electrically non-conducting element barriers, spaced apart along the feeding element. Between the element barriers, an active part of the surface of the feeding element is formed, which active part is in electric contact with the conducting medium. The element barriers have a substantial extension outwards from the active part of the surface of the feeding element into the first conducting medium, so as to homogeneize the current distribution along the active part of the surface of the feeding element.
