Abstract: Two methods are presented for determining the CEMF ( counter electromotive force) on operating aluminum reduction cells. Both methods employ a high speed electronic computer. The first method uses the residual valtage on the cell after the current has been dropped. By extrapolating back to the instant the current was dropped, an approximation of the CEMF can be obtained. Limitations of this method are discussed.The second and more accurate method employs the use of computer logic. In this method, if the resis…
