Research on Automatic Testing Technology for Cathodic Protection Potential in Long Distance Pipeline

Based on research on low power consumption filter and switch-off potential auto-diagnosis technology of long distance pipeline, made is a plan for auto-diagnosis and acquisition of cathodic protection switch-on potential and switch-off potential under low pipeline power consumption conditions. In-site test is satisfied, and the sample is developed. The technology will enhance cathodic protection control on operating pipelines, make cathodic protection measures more perfect and ensure pipelines operate properly. As a result, assessment of cathodic protection will be more accurate and scientific. The technology will bring significant benefits economically and socially.
