Research ArticleOpen accessIn the keywordsCorrelation Between Steady State and Impulse Earth Resistance ValuesN. Mohamad Nor, R. RajabThis study presented experimental results of earthing systems under low-magnitude currents and under high impulse currents. The details of the measuring circuit involved for both types of testing were described. Three field sites were selected. At each site, three earth electrodes configurations were used. This makes up to nine earthing systems. From both low magnitude and impulse tests, the correlation … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,736 accessesView PDFCite
Research ArticleOpen accessIn the keywordsValidation of the Calculation and Measurement Techniques of Earth Resistance ValuesN. Mohamad Nor, R. Rajab, K. RamarMuch research has been published in the literature on the mathematical approaches to obtain the most accurate earth resistance and resistivity values. However, the published research only conducted the comparisons among the mathematical/computational techniques and so far none has conducted validation tests of these mathematical/computational methods against the real earth resistance measurement at real field sites. Thus, the main contribution … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,214 accessesView PDFCite
