Abstract
The invention relates to a method and current measuring arrangement for measuring electric current flowing in an individual electrode in an electrolysis system. The electrolysis system comprises a plurality of interleaved electrodes (1, 2), cathodes (1) and anodes (2), arranged in an electrolysis cell (3) and immersed in electrolyte, said electrolysis system having a busbar arrangement (4) disposed on a separating cell wall (5) between each of the two adjacent cells. The busbar arrangement comprises an equalizer busbar (6, 7, 8, 9, 10, 11) to electrically connect anodes in one cell to cathodes in a next cell providing the current with multiple electrical pathways between electrodes, said electrical connection being formed by contact points (12) between the equalizer busbar (6, 7, 8, 9, 10, 11) and hanger bars (13) of the electrodes. The electric current in the equalizer busbar (6, 7, 8, 9, 10, 11) is measured by magnetic field sensing means (15, 16) arranged at measuring points (14) located between each pair of the adjacently neighboring contact points (12).
