Abstract

This paper presents the findings on the impulse characteristics of three types of soil by field measurements. A 2m × 2m grounding grid was installed for each site and was tested with 300kV, 10kA impulse generator. It was found that the resistance of low resistivity soil was found to be constant, and the resistance of high resistivity decreased with increasing current magnitudes. It is hoped that more effective earthing systems can be obtained in future, whereby taking consideration of the ionisation process in the soil in the design of earthing systems.
