Title: Periya Gopalan: Innovator in Cathodic Protection Design

Introduction

Periya Gopalan is a notable inventor based in Chandler, AR (US). He has made significant contributions to the field of cathodic protection design, particularly in the modeling of current and voltage distribution in concrete structures.

Latest Patents

Gopalan holds a patent for a "Cathodic protection design method, current mapping and system." This innovative method utilizes numerical techniques such as the finite element method (FEM) to predict the geometric arrangement of groundbeds and the optimal locations for electrical contacts in relation to the geometry of bridges and rebars. The system employs a magnetic sensor to detect the magnetic field generated by the cathodic protection current, along with a voltmeter or oscilloscope to measure the sensor's output. A current interrupter is also integrated to manage the CP current at the source. The mapping of current is achieved by moving the magnetic sensor across the concrete surface, ensuring uniform distribution throughout the structure. An advanced "expert" CP system is described, which is controlled by various current and environmental sensors, along with a dedicated microprocessor.
