The present invention relates to a system and method for monitoring, in real time, the electric current that passes through each one of a plurality of single cathodes or anodes forming an electrolytic cell. The system comprises a plurality of sensor means including Hall Effect sensors. The sensor means are arranged for current measurement and thermal drift correction. Such sensors are located in a sensor bar which includes a protecting shield which provides magnetic shielding and also prevents corrosion. The present invention enables a more accurate measurement of the current of each electric unit within the electrolytic cell (cathode or anode) by using a ferromagnetic barrier acting as a magnetic shield in order to reduce the effects of magnetic fields adjacent to the target one and by correcting the measurement based on heat factors that may alter the measurement.

摘要:
A steel-reinforced structure (1) supplied with an aqueous solution of an inhibitor (8) for the structure, is further protected against deterioration when an impressed cathodic current is applied; preferably the structure (1) is continuously bathed in the inhibitor solution (8); flow of the first impressed current is maintained until flow is relatively constant at a level at least one-half the level at which the first impressed current was initiated. The concentration of ions is sensed by measurement of the current flow while maintaining a chosen voltage. The inhibitor solultion (8) may be used in conjunction with an electroosmotic current to drive ions into the concrete and towards the steel; this may be done prior to applying the cathodic impressed current, or concurrently therewith by providing secondary electrodes (6, 7). Program controller means in the power station switches from one mode of delivery to another when current usage, measured by current density, is deemd to have become uneconomical.
