Impressed Current Cathodic Protection Systems - Houston

When large currents are needed or when high electrolyte resistivity prevents the efficient use of galvanic anodes, the protective current needed to make the structure cathodic may be obtained by applying low voltage dc current derived from normal AC mains supply. This is achieved by transformers/rectifiers which supply direct current to specially designed anodes which dissipate large currents without significant wastage.

This approach is used in impressed current systems. The major components of an impressed cathodic protection systems are the rectifier, positive and negative cables, and anodes. If the system is in soil, carbon "coke" backfill is an essential part that must be added.
