Keywords: a direct current gradient, model of pipelines, defect of a covering, electric field heterogeneity

On the basis of physical model of the pipeline the technique of interpretation of measurement results of voltage gradients is shown. The method of forecasting of isolation defect arrangement concerning a vertical axis of the pipeline is presented. The diagram for definition of electric field heterogeneity round the pipeline is developed.
