Special Issue Information

Dear Colleagues,

This Special Issue (SI) is devoted to presenting new developments and models as well as improvements in existing calculation methods in order to optimize the response of a grounding system to low-frequency fault currents and lightning strikes. The optimization includes the possibility of using materials other than copper for the construction of grounding electrodes, the assessment of ampacity and heating by the Joule effect due to the internal restance of the conductors, the effect of the grounding electrode damage due to oxidation, or the lack of contact with the conductive soil due to ground loosening. On the other hand, according to the soil conductivity model, any actions adopted to reduce the grounding resistance are also the subject of this SI. Additionally, any contribution to the optimization of lightning rod conductors in order to minimize the induced fields generated during lightning strikes is welcome. The topic is of great practical importance since it affects the safety requirements that the grounding system must meet. New models, improved calculations, new measurement techniques and other procedures are called to be published through this SI. Likewise, any input on non-destructive, non-invasive, and non-intrusive methods useful for checking the status of the grounding electrode will also be appreciated.

The measurement of the grounding resistance of grounding grids in large installations as well as grounding electrodes in urban areas is addressed in this article. The resistance value is obtained using a three-pin array by measuring the fall-of-potential on the ground surface. The resistance measured by this method is adjusted to its true value using a correction factor that aligns the measured resistance with the actual value. The proposed measurement method obtains correct values of the grounding resistance even when the auxiliary and potential electrodes of the tree-pin array are close to the electrode to be measured. Thus, it can be applied to large electrodes as well as electrodes in urban areas. Several simulated examples are used to illustrate the method, and some real cases with field measurements are presented for a final validation of the method. Full article
