High voltage overhead transmission lines (HVOHTLs) often pass close to metallic pipelines. The parallelism between HVOHTLs and pipelines, where electromagnetic fields couple them, may cause several problems. If the pipelines are metallic, a corrosion problem has occurred because these fields induce an AC voltage on the pipelines. This paper presents a novel contribution of a low electrical hazard that can control by grounding the pipelines with a polarization cells system to mitigate the induced AC voltage without deteriorating the cathodic protection (CP) performance. This work further utilizes a comparative analysis of two different mitigation units: a potassium hydroxide polarization cell (KOH-PC) and the solid-state polarization cell (SS-PC) to decide which one of these methods is more suitable for cathodic protection distribution. This paper also explores the potential of the hill-climbing algorithm in …
