Cathodic protection (CP) is a crucial technique for safeguarding metal structures from corrosion. In the context of modern infrastructure, digitalization plays a key role in enhancing the efficiency and effectiveness of CP systems. This paper explores an innovative approach to cathodic protection, focusing on the development of advanced technology that optimizes the output current of transformer rectifiers (T/Rs) through deep optimization techniques.

Traditional CP systems often operate without the flexibility to adapt to changing environmental conditions and structural requirements. The proposed technology leverages digitalization to remotely control T/Rs and fine-tune their output current. This adaptability is achieved by harnessing real-time feedback from IR-free potentials measured in critical test points of the CP system.

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.
