Frequency Domain Grounding Grid Analysis Based on the Finite Element Technique

In this paper a concise outline of a frequency domain grounding grid analysis based on the finite element technique is given. Weighted residual method is simultaneously applied to the scalar electric potential integral equation and to the electric field integral equation. The proposed approach represents a basis for development of electromagnetic models for time-harmonic grounding grid analysis as well as transient grounding grid analysis. In the case of transient grounding grid analysis, transformation from the frequency domain into the time domain can be obtained by Fourier transform.
