FIELD: aluminium production. SUBSTANCE: with electrolyzer voltage values in the range calculated from equation U = un + (0.048-0.495)B where un is nominal value of reduced voltage, stable decrease in aluminium oxide concentration in electrolyte is recorded, whereupon prediction of anode effect is stated. When lower voltage is detected, a change in interpole gap is stated. EFFECT: reduced periodicity of anode effects and power consumption; increased productivity. 3 tbl
