As a consequence, not only the corrosion of pipelines would be enhanced, but also the CP systems be affected significantly. The traditional CP criterion (-850mV(vs CSE)) was ineffective and a new CP criterion was in needed. The researches about effects of AC interference on CP parameters, such as CP potential，CP current density，Sacrificial anode potential，sacrificial anode consumption rate and sacrificial anode efficiency, were reviewed in this article. At the same time, the latest researches on CP criterions and AC corrosion mechanisms were introduced. Finally, the key problems were indicated and the development trend of this research field was predicted.
