Abstract

Measurement of the potential of a buried pipeline using the Cu/$CuSO_4$ reference electrode is the most widely used method for the estimation of the corrosion susceptibility of the pipeline. The recorded values, however, include inevitable errors due to the IR drop caused by the stray currents. In this paper, we describe the characteristics of the IR-free reference electrode used for more accurate measurement of the pipe line potential.
