摘要：

Possibilities of the method of noncontact measurements of current for the on-line assessments of the state of corrosion protection of different sections of a system of underground pipelines, the detection of places of improper insulation, and, in complex with contact electrometry, for the determination of the distribution of the current density of cathodic polarization and components of the transient resistance are shown.
