摘要（英）：

The invention relates to a method and a device (40) for filtering supply network failures (84) out from an electrode signal (82) in a metallurgical electro remelting method, in particular for the electrode distance regulation of an electrode distance control system (48) of a melting furnace (10). Said device also comprises at least one electrode sensor device (44) for measuring an electrode signal (82), in particular electrode current and/or electrode voltage of the electrode (30), a network sensor device (46) for measuring a network signal, in particular a network current and/or network voltage and a filter arrangement (50) for filtering network failures (84) of the network signal out from the electrode signal (82) such that an electrode signal (80) with no network failures can be emitted.
