– Can be used on large structures
– Can be used in areas with high levels of corrosion

Disadvantages
– Requires an external power source
– Can be more expensive than sacrificial anode systems

Sacrificial Anode Systems

Sacrificial anode systems use a more noble metal (often zinc or aluminum) than the structure you want to protect. The anode is connected to the structure and corrodes in its place, sacrificing itself to save the day.

Advantages
– No external power source required
– Less expensive than impressed current systems
– Easy to install

Disadvantages
– Less control over the level of protection
– Can only be used on small to medium-sized structures
