Abstract
Nowadays, natural gas in the Middle East has been discovered in extremely many quantities, and it is considered the most vital natural resource. Sometimes, the natural gas pipeline is constructed in the desert and paralleled with the high voltage overhead transmission lines (HVOHTLs). An induced AC voltage has appeared on the pipeline due to interfering with the HVOHTLs. Mainly, hydroxide potassium polarization cell (KOH-PC) has been applied to discharge this voltage to the soil within a safety limit. But, the mitigation units have negatively impacted cathodic protection (CP). The DC voltage of the pipeline is initially compensated using externally supplied impressed current cathodic protection (IMCP) units. In many cases, the external power sources have continuity and stability issues. Therefore, this paper presents different strategies as a promising solution to be utilized in reducing the disturbance of the …
