Abstract

Abstract:

Based on the analysis of the theoretical analysis methods of the impact characteristics of grounding devices at home and abroad,the influence of soil resistivity,impact current amplitude and horizontal layered soil on the impact grounding resistance of three-dimensional tower grounding devices was studied by using the CDEGS electromagnetic simulation software.Some common measures of impulse resistance reduction were put forward,which can provide reference for transmission line grounding engineering.

Key words: impulse grounding resistance, CDEGS simulation software, soil resistivity, impulse current amplitude
