A Galvanic Anode (also known as a sacrificial anode) is a key component in cathodic protection (CP) systems used to prevent corrosion of metallic structures. It operates based on the principle of electrochemical potential difference, where the anode material corrodes preferentially, thereby protecting the connected structure.
