Performance of Earthing Systems for Different Earth Electrode Configurations

Changes of behavior of earthing systems under high impulse conditions from its steady-state conditions have been found to occur in many studies. There are many factors that are thought to cause these changes. However, little studies so far have been conducted on the effects of earth electrode dimensions and configurations, particularly at field sites. This paper is to present and discuss the results of field site study on the performance of earthing systems of different configurations and dimensions.
