The electromagnetic method of non-contact current measurements makes it possible to quickly monitor the state of passive (insulating coatings) and active (cathodic polarization) corrosion protection of underground pipelines (UP); detect places of unsatisfactory insulation, determine the transient resistance and its components (resistances of soil, insulating layer, polarization) in different sections, the area of insulation damage, the current distribution of cathodic protection of UP. In combination with contact measurements of direct and alternating voltages, ohmic and polarization potentials, it is possible to determine the polarization resistance and estimate the corrosion rate.
