Some considerations regarding different earthing electrodes types and arrangements are discussed. The computation of the earthing resistance and voltage distribution, the designing, installation and testing procedures are evaluated and compared. Typical mistakes, inadvertences, wrong or incomplete procedures are outlined, e.g. the soil resistivity ...
