This standard applies to the design and construction of
foundation earth electrodes. The requirement for the installation
of such electrodes is set out in DIN VDE 0100-540 (VDE 0100-540),
DIN 18015-1, and in the Technische Anschlussbedingungen
Foundation/ring earth electrodes as specified here are designed to serve the following purposes:
- earthing of systems involving protective equipotential bonding via the main earthing busbar, as specified in DIN VDE 0100-540 (VDE-0100-540);
- functional equipotential bonding and functional earthing;
- potential grading in buildings, as specified in DIN VDE 0100-444 (VDE 0100-444) and DIN EN 50310 (VDE 0800-2-310);
- earthing of lightning protection and overvoltage protection systems.
The requirements specified for ring earth electrodes are also applicable in cases where such electrodes are to be installed on sites with existing buildings.
