Abstract (en)

[origin: US4448660A] A monitoring and control apparatus for flowing mercury electrolytic cells by measurement of the voltage drop in the shunted feed line of each electrode group comprising taps at the ends of a measured section of electrical bus bars for each electrode group electrically connected to a measuring means whereby the measured voltage drop is fed as an amplified signal to the measuring means, a control means set for a value from the total cell current divided by the number of taps comparing the actual measured values at various feed lines and a signal means activated when a set excess current is exceeded and to actuate the adjusters for a group of electrodes to lift the electrodes stepwise by an adjustable amount until excess current is not measured by comparison indicating that the feed line is no longer overloaded and a method of monitoring electric current in a mercury cell.
