Cathodic protection (CP) in both its forms of impressed and galvanic is becoming used in more countries and in greater quantities. The future of CP is bright if the systems presently being installed do provide long-term performance; that is, they keep passing current evenly through the concrete for a long time to the protection criteria of an applicable standard. In certain areas, such as North America, this level of performance has not been reached, and in other countries, there is an uneven set of performances, so one of the most important aspects in the future success of CP is that appropriate CP installations are made in the future, and they are demonstrated to be working in accordance with relevant standards.
