Abstract

Anodestremovervåkning i aluminiumelektrolyseceller Søknaden vedrører en framgangsmåte og en anordning for individuell overvåkning av anodestrøm i aluminiumelektrolyseceller med forbakte anoder hvor strømmen måles kontinuerlig og hvor strømmålingene vises i sann tid på et display hvorved strømstyrken for hver anode kontinuerlig kan avleses.Anode Current Monitoring in Aluminum Electrolysis Cells The application relates to a method and apparatus for individually monitoring anode current in aluminum electrolysis cells with preceded anodes where the current is continuously measured and where the current measurements are displayed in real time on a display whereby the current of each anode can be continuously read.
