The effect of cathodic protection by the sacrificial anode attached to condenser waterbox of power plant was investigated using numerical analysis. The condenser is consisted of various materials. So in case of no protection, the serious galvanic corrosion between waterbox and tubesheet was observed. If sacrificial anodes were attached to the wall of waterbox or the area corroded galvanically, the large protection effect was showed. To demonstrate the validity of numerical analysis results, model test was executed. The numerical solution was consistent with the experimental vague well.
