Abstract: | The objective of this work is to provide a simplified model to analyse the electromagnetic emission of the grounding grid thus enabling engineers to perform parametric studies rapidly without greater loss of accuracy. The proposed approach is based on the use of the transmission line theory and the concept of dipole radiation in the presence of a lossy half‐space including the Sommerfeld integral approach. The model proposes to determine the electromagnetic fields (soil and air) and current distribution in a grounding system. The proposed model is described and illustrated with applications. The limitations and advantages are also discussed and compared against antenna theory counter parts. Copyright © 2014 John Wiley & Sons, Ltd. |
