Solution potentials and their interpretation in PIPELINE: Cathodic Protection Part 2

It is often difficult to decide whether a value is a cathodic or an anodic potential, and the method of identification is described in some detail in this concluding article. In another section the author deals with interference to cathodic protection systems caused by stray currents, and provides some very interesting practical data regarding problems he has investigated. Other subjects covered include a detailed description of the ground wire method of taking potential measurements, and the use of solution potential measurements for plotting the direction of stray currents.
