I researched a master’s thesis at the College of Engineering at the University of Basrah (Wireless Monitoring of Cathodic Protection in Remote Sites) by the student Hassan Faleh Faisal
The research dealt with a comprehensive study of the cathodic protection technology and considered it an effective way to reduce the corrosion of metal structures first, and then build a cathodic protection system that works by forced current consisting of: a conventional source of DC current, a carbon steel tube (cathode electrode), anode of aluminum electrodes, as well as a reference electrode Of the saturated calomel, the behavior of this system was studied under the influence of four different factors: the temperature of the solution, the amount of dissolved oxygen, the distance between the anode and the cathode, the pH value) and the voltage and current values necessary for protection were measured and recorded during the change of these factors to show the extent of their impact
In the second part of this study, the traditional power source was replaced by solar cells for the purpose of passing the electric current to the system, as we can make these cells a good alternative in remote areas exposed to the sun permanently. In addition, a practical control system was proposed to adjust the tube voltage at the required amount. The practical results proved The cathodic protection current increases significantly with the increase in the temperature of the solution, and the amount of dissolved oxygen, and to a lesser extent with the increase in the distance between the anode and the cathode. The cost of going to remote places to check each system separately.
