External cathodic protection of well casing Ingestion-build-93833 The calculation of the short-circuit

The calculation of the short-circuit currents based on the rated data of the electrical equipment and the topological arrangement of the system has the advantage of being possible both for existing systems and for systems at the planning stage

This correlation is based on the classification into two groups of both actions and final effects

External cathodic protection of well casing Ingestion-build-93833 The calculation of the short-circuit1 Scope This European Standard specifies methods used to evaluate the external corrosion hazards of well casings, as well as cathodic protection means and devices to be implemented in order to prevent corrosion of the external part of these wells in contact with the soil. This European Standard applies to any gas, oil or water well with metallic casing, whether cemented or not. However, in special conditions (shallow casing: e. g. 50 m, and
