Potential Theory Applied to Cathodic Protection Design, 2nd Edition

Potential Theory Applied to Cathodic Protection Design provides the mathematical development of analytical equations for the design of cathodic protection (CP) systems for underground structures with anode groundbeds havinge various configurations. Equations include calculations for the resistance and voltage (potential) and will assist the CP design engineer. All the previous references on this subject matter (including NACE CP courses) utilize equations developed almost a century ago by Sunde and Dwight for electrical grounding systems. This book also has a methodological approach, showing detailed developments and practical examples to the equations. The book is unique in the presentation of the theory that justifies the development of equations to design and simulate CP systems. The book provides the methodology to develop new equations with more specific uses, if required. The first edition of Potential Theory Applied to Cathodic Protection Design showcased the mathematical development of analytical equations for the design of cathodic protection (CP) systems for underground structures with anode groundbeds having various configurations. Equations included calculations for the resistance and voltage (potential) to assist the CP design engineer. This second edition has several important changes including updates on integral and analytic solutions for horizontal anodes in the same trench, an approach that was insufficiently developed in the first edition. Other updates include: ¿Generalization of groundbed resistance combining the equation for anodes with different length and depth, with the equation for different distance between anodes. ¿Calculation of anode's current in a groundbed, based on the crowding factor. ¿Generalization of groundbed resistance combining the equation for anodes with different length and depth, with the equation for different distance between anodes. ¿Calculation of anode's current in a groundbed, based on the crowding factor. ¿By means of the use of integral formulations, particularizes the use of the APM for any combination of underground anode systems.
