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.
