The invention is a method for testing the anode drop of an aluminum electrolytic cell, relates to a method for measuring and analyzing the anode drop of the aluminum electrolytic cell in industrial field, characterized in the root of an anode steel stud is weld with a steel bar at the phosphorus iron before anode changing, a steel bar is knocked into a carbon bowl besides the edge of the carbon bowl on an anode carbon block, the steel stud drops Vstud1 to Vstud4 of the studs and the iron-carbon drops Viron-carbon1 to Viron-carbon4 of the carbon bowls are measured, the corresponding carbon block drops Vcarbon-block1 to Vcarbon-block4 are measured, the anode carbon block bottom is hooked by an anode hook, and the total anode drop Vanode composed of Vstude, Viron-carbon and Vcarbon-block is measured. By processing the anode to be measured, the anode steel stud drop, the iron-carbon drop and the anode carbon block drop as well as the change relation can be simply and effectively measured and analyzed, thus to guide aluminum electrolysis production and develop energy saving and consumption reduction.
