FIELD: method is used for measurement of polarization potential of current conductive underground structures during control of structures corrosion protection. SUBSTANCE: structure is subjected to action of periodical single polar pulsed current with duration of pauses between pulses from 1-10 sec. to 1-10 sec. and polarization potential in pauses between pulses is measured. EFFECT: increased accuracy of electrical current polarization potential measurements. 4 dwg
