This invention relates to assess of the adequacy of a cathodically protected underground pipeline with consideration of AC corrosion. A steel probe and a CSE are installed near the pipeline at depth. The steel probe is electrically connected to a pipeline. The measurements of AC probe currents flowing between a steel probe 2 and a pipeline 1 are performed simultaneously with those of on- and off-potentials, and DC probe currents.
La présente invention a trait à l'évaluation de la qualité de la protection cathodique d'un pipeline souterrain relativement à la corrosion due au courant alternatif. Une sonde en acier et une électrode de sulfate de cuivre (CSE) sont installées près du pipeline en profondeur. La sonde en acier est raccordée électriquement à un pipeline. Les mesures effectuées par la sonde c.a. des courants s'écoulant entre une sonde en acier (2) et un pipeline (1) sont réalisées simultanément avec celles des potentiels circuit fermé et circuit ouvert et les mesures de la sonde c.c.
