An arrangement for determining the height position of a vertically movable electrode (2) in an arc furnace (1). The arrangement includes an elongated, flexible element (9), preferably a heavy chain, whose one end is attached to a first attachment point on the movable electrode (2). The other end of the chain is attached to a fixed second attachment point. The total weight of those flexible element parts that are carried by the movable and the fixed attachment points respectively will vary in response to vertical movement of the electrode. The arrangement also includes means (6) for sensing that part of the total weight supported by the fixed attachment point, for determining the height position of the electrode (2). The invention also relates to a method of determining the height position of a vertically movable electrode.
