Rust Prevention in Structural Establishments using Cathodic Protection Technique Driven by an MPPT based Solar Charge Controller

This paper is aimed at the implementation of a novel technique to prevent the formation of rust in structural establishments. The existing metallic structures usually exceed their original design lifetime and hence require a potent protection mechanism for a rust-free life extension. The Impressed Current design of Cathodic Protection coupled with simple design features, installation procedures and cost effectiveness presents an ideal technological solution to the prevalent issue of rusting and subsequent degradation of structural establishments. This method makes use of the abundantly available Solar Energy for battery charging, which provides the required impressed current for cathodic protection. In this method, Maximum Power Point Tracking based digital charge controller is employed to ensure maximum charging efficiency and economic feasibility. The charging module is operated in buck configuration to maximize the rate of charging. This enhanced design of Impressed Current Cathodic Protection ensures precise, standard industrial levels of protective current in metallic structures used in infrastructure and commercial buildings. This process provides sufficient protection to metallic structures by ensuring efficient transfer of electrical current through the structure’s concrete sections. A suitable anodic material is cast onto the top surface of the concrete slab present above the steel frame structure. The experimental results indicate the effectiveness of the proposed design in terms of ease of design, economic considerations and superiority over existing models. The proposed model exhibits extreme potential to inhibit rust formation which can be adopted for various industrial applications.
