Beschreibung
Zusammenfassung:	The paper presents an experimental determination of the grounding grid impulse characteristics procedure. The measuring circuit configuration and characteristics of the applied equipment are given. Some of the numerous experimental results for three grounding grid configurations are presented. The paper provides the analysis of the results obtained for various impulse current shapes, magnitudes and discharge points. The results shown are related to the cases without soil ionization around the grid elements.
