Abstract Writing with long experience of electricity production and distribution units, the author first comments on the amendments concerning earthing in the Swiss ordinance on heavy current and after a few general remarks goes on to deal with the following aspects: electrical resistance of the earth; different types of earth connections; measurement of voltage distribution and of earth resistance; influence of the depth of electrode placement in the earth on the contact and step voltage; calculation of artificial earthing installations; combination of various earth electrodes for control of the potential; effect of an electric current on the earth connection; materials for earth electrodes and problems of corrosion; calculation and measurement of loss currents to earth in 16kV installations.
