On a site of the pipeline in diameter of 530 mm influence of the direct current proceeding on metal of a pipe on displacement of potential «pipe - earth» is investigated. Dependences of displacement of potential at most a current are established. The received dependences are necessary for considering at carrying out of electromeasurements on underground pipelines.
