What does anode efficiency measure?

Anode efficiency specifically measures how effectively the anode material is utilized when providing cathodic protection. It assesses the ratio of the amount of metal consumed that actually contributes to creating the required protection current against the total amount of anode material consumed. A higher ratio indicates that a greater proportion of the metal is effectively used for its intended protective purpose, minimizing wastage and maximizing the longevity and efficacy of the cathodic protection system. This is crucial for evaluating the performance and economic viability of anodes used in various corrosion prevention applications.

In contrast, other options address different aspects or types of protection systems. For instance, one option pertains to cathodic protection current rather than directly measuring anode effectiveness. Understanding anode efficiency is vital for engineers and technicians in the field, as it directly impacts maintenance strategies and cost management regarding cathodic protection systems.
