Abstract
This work presents a system to detect short and open circuits suitable for Optibar® inter-cell bars in copper electrorefining processes. The system is based in Optibar´s voltage connecting segments. Voltages are sampled and transmitted via WI-FI to a compatible SQL database every five minutes. The technique proposed performs sliding window analysis on anode-cathode voltages slopes to detect short and open circuits. The system was implemented in a refinery section of 20 cells with 1,100 cathodes.
