摘要
The method for determining the interactions due to direct currents on neighboring buried metallic structures (101, 102) at least one of which is connected to a direct current generator such as a cathodic protection device, consists in placing in the vicinity buried metallic structures (101, 102) of calibrated control metallic specimens (105, 106) made of materials similar to those of the structures (101, 102). The test pieces (105, 106) are spaced from each other at a distance equal to the distance l separating the structures (101, 102). The reference metal test pieces (105, 106) are placed in the immediate vicinity of the reference electrodes (107, 108) and the potentials of the control test pieces (105, 106) are simultaneously measured relative to the reference electrodes (107, 108) and on the other hand the intensities of the currents flowing through the calibrated control specimens (105, 106) when these are electrically connected respectively to each of the structures (101, 102).
