EQUIPOTENTIALITY OF THE CHASSIS-EARTHS AND EARTHS

All the metal chassis-earths are bonded together and then bonded to the earth to help protect the installation against arcing. Indeed, the presence of several independent earthing networks close to one another may lead to a significant difference in potential which could prove hazardous for both people and property. If this is the case, the different earth networks must be interconnected, either via the underground earth or by special buried bonds, to ensure equipotentiality.

PIPELINES

Made of steel and covered with an anti-corrosive coating, pipelines are designed for transporting oil. To ensure maximum safety, the buried parts of pipelines are also equipped with cathodic protection to prevent chemical or electrochemical corrosion.

CATHODIC PROTECTION

To reduce the potential of the pipes to the required value, the network is connected at one or more points to the negative pole of a DC current source. This negative voltage is achieved by connecting a DC power supply between the pipeline and the ground, thus creating a current outside the "earthing" flowing through the ground and then in the pipeline. In this situation, the pipeline serves as the cathode for the circuit.
