ABSTRACT:
A method and apparatus for measuring the polarization potential of anodically protected metal structures in moist soil in a current field utilizes auxiliary electrodes and a reference electrode immersed adjacent the metal structure in the same soil. The auxiliary electrodes are connected to the metal structure, then disconnected, and the electrical potential between the auxiliary electrodes and reference electrode is measured immediately after the disconnection.
