There’s a growing challenge of accurately identifying rectifier ripple within cathodic protection systems and distinguishing it from genuine AC interference on buried pipelines. As grid modernization pushes more high-voltage lines underground, operators face rising exposure to both AC and DC influences that can destabilize protective conditions and accelerate corrosion.
This whitepaper explains the electrical signatures produced by different rectifier types, why ripple often mimics induced AC, and how misinterpretation can lead to wasted mitigation efforts or overlooked hazards. Aligned with AMPP/NACE criteria, it also provides a practical framework for evaluating risk, improving diagnostic accuracy, and strengthening integrity management programs as electrical infrastructure continues to evolve.
