Influence of Conductor Segmentation in Grounding Resistance Calculation Using Boundary Element Method
This paper presents differnt models of conductor segmentations in grounding resistance calculation of simlple geometry (finite straight rod). Grounding resistance is calculated using Boundary Element Method (BEM)and results are compared with results obtained by analitical equation and proffesional CDEGS (Current Distribution Electromagnetic Interference Grounding and Soils Structure Analysis) software, which use Moment Method.Simple algorithms and programs are developed for calculating grounding resistance using integral equation method. Examples and results related to the several different types of conductor division into segments (rings and sticks) are presented for grunding resistance and surface leakage current density. The straight rod is 1m-lenght conductor with cirular cross section 1 cm radius, deeply burried in soil conductivity 0.01 S/m. The accuracy of different segmentation types is compared with low frequency module of well-known CDEGS software. Summarized results of grunding resistance for different approaches and analytical equation are presented
