METHOD OF MEASURING POLARIZATION POTENTIAL OF UNDERGROUND STRUCTURE Russian patent published in 1994 - IPC

Abstract RU 2023053 C1

FIELD: protection of underground structures against corrosion. SUBSTANCE: electrochemical potential detector is subjected periodically to polarization. Polarization potential of the detector is measured in intervals between polarization cycles. Potential is memorized. Duration of polarization interval is adjusted depending on results of comparison of values of polarization current in potential detector circuit measured at specified time interval. EFFECT: improved precision of measurement. 2 dwg
