Abstract
A method and apparatus are disclosed for measuring the current distribution in an alumina reduction cell. The apparatus includes sensors attached to the anodes of the cell, a remote computer system for receiving and correlating data received from the sensors and a means for transmitting and receiving the data from the sensors to the remote computer.
Claims10
A method for determining current distribution among the anodes of a single alumina reduction cell comprising concurrently measuring individual current levels at a selected plurality of said anodes within said cell, transmitting said individual current levels to an electrically isolated computer and calculating the current distribution within said cell based upon said individual current levels.
The method of claim 6 wherein said optimizing comprises raising and/or lowering certain anodes within said cell.
