A Smart Cathodic Protection Management: Advanced Technology for Optimizing Output Current in T/Rs

Abstract Cathodic protection (CP) is vital for preventing corrosion in metal structures. Modern infrastructure benefits greatly from digital enhancements, improving CP system efficiency. This paper introduces an innovative CP approach, focusing on advanced technology that optimizes transformer rectifier (T/R) output currents through deep optimization techniques. Traditional CP systems lack the flexibility to adjust to environmental changes and structural needs. The proposed technology leverages digitalization to remotely control T/Rs and fine-tune their output current. Adaptability is achieved via real-time feedback from IR-free potentials measured at critical CP system test points. Key components of this novel approach include the integration of remote monitoring units (RMUs), which are powered by small solar panels, and their ability to collect and transmit real-time data from critical test points. By analyzing this data, the system can make rapid and accurate adjustments to the output current, ensuring optimal corrosion protection. This leads to a significant reduction in energy consumption, as the T/Rs can operate at their most efficient levels. Furthermore, it enhances the lifespan of anodes and reduces maintenance costs. The RMUs and deep optimization algorithms also provide a proactive approach to maintenance by detecting potential issues before they become critical, ensuring at any time effective corrosion protection.
